The Evolution of the One-Armed Bandit

Top Online Slot Games with the Best Bonus Features in 2025

Tired of complicated games with long rulebooks? Slot games offer pure, instant fun with just a spin of the reels. You simply set your wager, click the button, and watch symbols align for a chance to win, with features like wilds and scatters adding exciting surprises. It’s one of the easiest ways to enjoy gaming, offering effortless entertainment and quick rewards with every click.

The Evolution of the One-Armed Bandit

The Evolution of the One-Armed Bandit transformed slot games from purely mechanical luck into interactive entertainment. Early machines forced physical lever pulls to spin reels, limiting pace and strategy. Modern digital slots retain the lever as a nostalgic feature, but games now prioritize button-based controls that allow autoplay and faster rounds. A key practical shift involved replacing physical reel strips with virtual reel mapping, enabling larger symbol sets and multi-line payouts without mechanical constraints.

This change lets modern slot games offer 1,024 ways to win on a single spin, a density impossible for the original one-armed bandit.

For today’s player, understanding that the lever is now a cosmetic toggle—not a functional necessity—helps you focus on volatility and bonus triggers rather than physical interaction. Always check the paytable to see if a lever-triggered feature exists, as some games still tie it to a unique mini-game.

From mechanical reels to the first digital interfaces

The leap from purely mechanical reels to the first digital interfaces fundamentally altered player interaction. Early electromechanical models, like those in the 1960s, still used physical spinning drums but replaced the lever with a button, a move toward simplicity. The true shift, however, arrived with video slots in the mid-1970s, which replaced physical reels entirely with a cathode-ray tube display. This change allowed for digital reel programming, enabling designers to weight symbol outcomes and introduce complex payline structures impossible with spinning hardware. Suddenly, a game’s behavior no longer depended on moving parts, but on software logic running beneath a static screen. Players faced a monitor instead of a window into gears, marking a clean break from the tactile slot of the past.

How video technology transformed the classic fruit machine

Video technology replaced the mechanical reels and lever of the classic fruit machine with a digital RNG and a screen, enabling dynamic multi-line payout structures. This shift allowed for complex, themed animations and bonus rounds—such as cascading wins or pick-a-prize games—that physical reels could never simulate. The classic single payline expanded into dozens of virtual lines, while wilds and scatters became standard. Video also introduced interactive features like gamble-ladders, fundamentally altering player engagement from passive spinning to strategic decision-making within the game itself.

The rise of online platforms and mobile adaptation

The rise of online platforms and mobile adaptation fundamentally reshaped the slot experience by eliminating physical presence. Players can now access a vast library of titles directly from a smartphone or tablet, allowing for short, casual sessions anywhere. This shift required developers to prioritize mobile-first interface optimization, redesigning layouts for vertical screens and touch controls without compromising game mechanics. The transition from mechanical reels to digital code enabled instant spin results, auto-play features, and variable bet sizes, all tailored to the on-the-go user. Practical adaptation includes responsive graphics that scale across device sizes and simplified menu navigation for one-handed use.

Core Mechanics That Drive the Action

The core action in slot games is driven by the Random Number Generator (RNG), a microchip algorithm that cycles thousands of numbers per second, determining each spin’s result independent of previous outcomes. The payline structure defines winning combinations, with mechanics like cascading reels replacing symbols to create multiple wins from a single spin. Hold and Spin features lock specific symbols in place for respins, while collector mechanics gather values from triggered features. A critical mechanic is the hit frequency, which dictates how often a spin yields a payout, directly influencing perceived volatility and reel activity.

Understanding paylines, symbols, and reel structures

Mastering slot games begins with understanding paylines, symbols, and reel structures. Paylines define winning patterns across reels, ranging from fixed single lines to hundreds of “ways-to-win” where adjacent symbols pay regardless of position. Symbols include standard icons, high-value themes, and special symbols like wilds and scatters that trigger bonuses. Reel structures vary, such as classic 3×3 grids or modern video reels with cascading mechanics. Each component directly dictates hit frequency and payout potential. A comparative table clarifies these differences:

Aspect	Traditional	Modern Video
Paylines	Fixed, limited (1–50)	Dynamic, high (243–1,024)
Symbol Function	Basic matching	Wilds, scatters, multipliers
Reel Structure	Static 3–5 columns	Cascading, expanding grids

How random number generators guarantee fair outcomes

At the heart of every spin, a Random Number Generator (RNG) constantly produces thousands of number sequences per second. When you press play, the RNG snatches the exact millisecond’s code, instantly mapping it to a specific reel outcome. This ensures each result is entirely independent from the last, creating true unpredictability. The system uses a seeded algorithm to generate these pseudorandom outcomes, which are rigorously tested by third parties to confirm they mimic true randomness. Because the RNG cycles ceaselessly, no pattern can form, and no external force can influence the result at the moment you spin.

Return to player percentages and house edge explained

In slot games, Return to Player percentages (RTP) tell you the theoretical payout over millions of spins—for example, a 96% RTP means the game keeps 4% as its house edge. This house edge is the casino’s built-in profit, meaning you lose that percentage on average long-term. Higher RTP (97%+) gives you more of your bet back, while lower RTP (94%) boosts the house edge. Always check a slot’s RTP in its info panel to choose games that stretch your bankroll and reduce the edge working against you.

Exploring Popular Themes and Visual Styles

Exploring popular themes and visual styles in slot games means analyzing how specific aesthetics—like ancient Egypt’s gold-and-sand palettes or cyberpunk’s neon grids—directly influence player engagement. For example, a high-volatility game often uses dark, brooding imagery to reinforce the risk-reward loop, whereas lighthearted fruit slots employ bright primaries and simple shapes to signal fast, casual play.

Always match visual density to mechanic complexity: a cascading-reels game benefits from layered, parallax backgrounds, while a classic three-reeler should stay flat and iconic to avoid cognitive overload.

When selecting a theme, ensure every art element—from reel symbols to ambient animations—supports the core emotional hook, whether that’s nostalgia, adventure, or suspense.

Adventure, mythology, and cinematic franchises

Adventure, mythology, and cinematic franchises in slot games transform spinning reels into narrative-driven experiences. Adventure themes often use progressive maps where wins unlock new locations or treasures, employing exploration-based bonus rounds for engagement. Mythology slots integrate pantheon hierarchies, with Zeus or Thor acting as wild multipliers tied to specific godly attributes. Cinematic franchise slots replicate film scenes through synchronized reel animations and licensed soundtracks, using character-specific symbols to trigger iconic movie moments rather than standard paylines.

Adventure slots use cascading reels to simulate journey progression across multiple stages.
Mythology themes assign unique reel mechanics to each deity, such as Odin’s wild-nudging ravens.
Cinematic franchise slots edit full film clips into 3-reel sequences for feature unlocks.
Combined themes appear, like an Indiana Jones slot merging relic-hunting archaeology with temple-run mythology.

Seasonal motifs and pop culture tie-ins

Seasonal motifs in slot games leverage holidays like Christmas or Halloween, swapping standard symbols for themed icons such as snowflakes or pumpkins to create immersive experiences. Pop culture tie-ins, meanwhile, license recognizable franchises—from blockbuster movies to iconic TV shows—integrating characters and soundtracks directly into reel mechanics. This fusion boosts player engagement through familiarity and limited-time events. Pop culture slot collaborations often feature branded bonus rounds or progressive jackpots tied to a franchise’s narrative. Q: How do seasonal motifs differ from pop culture tie-ins? A: Seasonal motifs cycle annually around calendar events, while pop culture tie-ins are evergreen partnerships based on specific intellectual property, like a Marvel or Game of Thrones slot.

The role of animation and sound design in player engagement

Animation and sound design directly drive player engagement in slot games by reinforcing reward feedback loops. When a winning combination lands, cascading reel animations and celebratory auditory cues, such as chimes or escalating tones, create a visceral loop of anticipation and satisfaction. This sensory pairing signals success and encourages continued play. A clear sequence governs this engagement:

A distinct audio cue precedes a major feature, priming the player for action;
Corresponding on-reel animations then visualize the event, such as expanding wilds or triggered free spins;
Finally, celebratory sound effects and particle animations punctuate the outcome, delivering closure and a dopamine hit.

Poorly synced animations or repetitive audio can break immersion, causing players to disengage instantly.

Special Features That Boost Excitement

The reels spin, and then a golden border locks into place—a Sticky Wild takes hold, refusing to budge for the next several spins, each new cascade fueling your growing anticipation. Suddenly, the screen shatters into a Megaways explosion, offering thousands of paylines where only a few existed before. A cascade might deliver a multiplier that feeds into a progressive win meter, turning a simple sequence into a chain reaction of escalating rewards. A scatter lands on the top row, triggering a free spins round where every win is doubled, and the sticky wilds multiply with each spin. Your heart races as the respins shuffle lower-paying symbols away, leaving only high-value icons on the grid.

Wilds, scatters, and expanding multipliers

Within slot games, Wilds, scatters, and expanding multipliers are core mechanical triggers for heightened payout potential. Wilds substitute for regular symbols to complete winning lines, while scatters typically activate bonus rounds or free spins regardless of their position on the reels. Expanding multipliers, often tied to wilds or scatters, increase the value of wins they touch, sometimes multiplying the entire payout by a set factor during a feature. These elements work in concert to create layered win conditions beyond standard paylines.

Wilds substitute, scatters trigger features, and expanding multipliers amplify wins, forming the foundational trio for boosted slot excitement.

Free spins rounds and their strategic triggers

Free spins rounds are a premier special feature, but knowing their strategic triggers elevates gameplay. The most common trigger is landing three or more scatter symbols anywhere on the reels. To activate these rounds strategically, follow this sequence:

Identify games where scatters pay in addition to triggering spins.
Adjust your bet size to remain eligible for the highest multiplier potential within the free round.
Look for games that allow retriggering during the bonus, extending your play without extra cost.

Prioritizing these triggers turns random luck into a calculated advantage.

Bonus games, pick-me features, and interactive mini-events

Bonus games, interactive pick-me features, and mini-events transform standard spins by inserting strategic player choices. A typical sequence involves first triggering a bonus round via scatter symbols, then selecting from a grid of hidden items. This pick-me mechanic directly reveals instant credits or multipliers, escalating engagement. Interactive mini-events, such as shooting targets or solving quick puzzles, then award cumulative prizes.

Trigger bonus round with specific symbol combinations.
Choose from multiple hidden objects to reveal prizes.
Participate in a skill-based mini-event to multiply winnings.

These elements break repetitive reel-spinning, placing short-term decision-making and immediate feedback at the core of the experience.

Progressive Jackpots and Payout Structures

The first time I saw the meter climb on a progressive slot, I felt the tension—every spin feeding a pool that could hit at any moment. These jackpots grow from a tiny slice of each wager across linked machines, often splitting into tiers like Mini, Major, and Mega with escalating payouts. A common question is: How does the game decide when to pay the top prize? The answer is that the jackpot triggers randomly, usually independent of bet size, though some slots require maximum coins to qualify for the grand. While the main pool resets to a base amount after a win, the lower tiers rebuild quickly, keeping the chase alive.

Networked pools versus standalone jackpot systems

In slot games, the choice between networked pools and standalone jackpot systems mostly affects how big the prize can get and how often it hits. A networked pool jackpot links multiple machines or even casinos together, allowing the prize to grow rapidly from many players’ bets, but it also means you’re competing with far more people for the win. A standalone jackpot, on the other hand, is confined to a single machine, so the prize stays smaller and often triggers more frequently. Here’s a quick breakdown:

Networked pools: big potential prizes but lower individual odds of winning per spin.
Standalone systems: smaller, more frequent wins with better chances on a single machine.

Your choice depends on whether you prefer chasing life-changing sums or enjoying steadier, smaller payouts.

How bet size influences top prize eligibility

In progressive jackpot slots, bet size directly gates access to the top prize. Many games require a maximum qualifying bet to activate the jackpot tier; wagering below this threshold only unlocks smaller fixed prizes. The logic is that the jackpot meter incrementally grows from a small portion of each coin-in, so larger bets contribute proportionally more to the fund. Paradoxically, a player wagering the minimum stake may see the jackpot display tick up from others’ spins but remain personally ineligible to win it. Thus, the best chance at the top prize always hinges on matching the game’s specific bet requirement.

Q: Does every progressive slot require max bet for the jackpot?
A: No—some use a fixed trigger regardless of bet size, while others scale the prize tier based on your wager level. Always check the paytable for “jackpot on this bet” conditions.

The psychology of near-misses and big win anticipation

Near-misses in slot games—where two jackpot symbols land and the third stops just short—trigger a powerful psychological rush. Your brain interprets the loss as a “close win,” releasing dopamine in a pattern similar to an actual payout. This fuels big win games not on gamstop anticipation, making you believe the grand prize is imminent. Progressive jackpots amplify this effect; as the pot grows, every near-miss feels more significant, and the chase intensifies. The anticipation itself becomes a reward, driving continued play as your mind tricks you into thinking you almost “cracked the code.”

Near-misses and escalating jackpot totals warp your perception, replacing rational loss with thrilling anticipation that the next spin could finally deliver the big win.

Volatility and Hit Frequency Dynamics

In slot games, Volatility and Hit Frequency Dynamics dictate the rhythm of play, balancing risk against reward. High volatility slots deliver rare but sizable payouts, while low volatility games bombard you with frequent small wins, keeping your balance stable. The hit frequency is the percentage of spins that result in any return, directly influencing your session endurance—a low hit rate with high volatility demands a larger bankroll to absorb dry spells.

A low-volatility slot with a high hit frequency may feel satisfying but rarely funds a monumental win, whereas chasing a progressive jackpot often means enduring a dreadfully low hit rate.

Understanding the dynamic interplay helps you pick a game that aligns with your tolerance for expectation and variance.

Low, medium, and high variance categories defined

In slot games, variance defines the risk-reward profile. Low variance slots deliver frequent, small wins, keeping your bankroll steady with predictable, minor payouts. Medium variance strikes a balanced middle ground, offering a mix of modest and moderate wins with a safe tempo of smaller hits and occasional larger payouts. High variance slots are the polar opposite, featuring long dry spells punctuated by infrequent, massive jackpots. Players choosing low variance accept small gains for extended play, while high variance chasers risk significant bankroll swings for life-changing prize potential.

Matching volatility to player risk tolerance

Matching volatility to player risk tolerance begins by identifying a player’s appetite for variance before they spin. Low-volatility slots reward frequent, modest wins, suiting those who prioritize extended play over big jackpots. Conversely, high-volatility games deliver rare, oversized payouts, appealing to thrill-seekers who can withstand dry spells. Developers enable this alignment by offering detailed volatility ratings within game menus or paytables. Players can then consciously select a slot where the swing pattern matches their emotional comfort zone, ensuring every session feels rewarding rather than frustrating. This dynamic match prevents bankroll burnout and enhances engagement.

Matching volatility to player risk tolerance ties the game’s payout rhythm directly to a player’s comfort with risk, making low-volatility slots ideal for steady players and high-volatility slots perfect for those chasing big, rare wins.

Session length and bankroll management implications

Session length directly dictates necessary bankroll size, as higher volatility slots require longer sessions to endure dry spells without depleting funds. A tight bankroll paired with extended play on low-hit-frequency games risks rapid exhaustion; conversely, short sessions on volatile machines may end before a payout window. Effective management means aligning session duration with the game’s hit frequency—low volatility allows longer play on smaller bankrolls, while high volatility demands larger reserves for sustainable bankroll management across fewer spins. Balancing these factors ensures the session neither finishes prematurely nor forces excessive financial exposure.

Mobile Play and Touchscreen Optimization

Mastering mobile slot play starts with touchscreen optimization that mimics physical button feedback through responsive haptics. The reels must spin with a flick, not a tap, while oversized spin buttons are placed thumb-friendly zones for one-handed gameplay. A dynamic tilt sensor can trigger bonus mini-games by simply rotating the device, eliminating cluttered on-screen controls. Smooth gesture controls let you swipe to adjust bet sizes or slide to reveal hidden multipliers, keeping the action fluid. Every element, from the virtual reels to the payout display, scales instantly to your screen’s resolution without lag, ensuring each touch feels immediate and intentional.

Responsive design versus dedicated app experiences

For slot games, responsive design versus dedicated app experiences hinges on native performance versus browser flexibility. Dedicated apps utilize device-specific APIs to deliver smoother reel animations, haptic feedback on spins, and persistent offline access to game states. Responsive web versions bypass installation, allowing instant play on any screen size, but may incur latency on complex particle effects during bonus rounds. A clear sequence for selecting between them:

Assess whether low-latency touch response is critical for gameplay mechanics like rapid autospin cancellation.
Confirm if offline features, such as cached free-spin rounds, are needed.
Evaluate device storage constraints; responsive design avoids app footprint entirely.

Apps provide superior control over touch calibration, while responsive sites prioritize cross-device continuity.

Thumb-friendly controls and portrait mode adaptations

For slot games, thumb-friendly touchscreen layouts reposition spin buttons and paytable toggles within the lower third of the display, where thumbs naturally rest during portrait hold. Portrait mode adaptations reflow reel grids from traditional 5×3 to vertical 3×3 or 3×5 configurations, ensuring full visibility without horizontal scrolling. The auto-spin trigger is often redesigned as a long-press action rather than a small icon, preventing accidental stakes changes. Bet adjustments are clustered near the thumb’s arc, typically using sliding gestures instead of tiny +/- symbols.

Spin button placed within bottom 30% of screen height for one-handed access
Vertical reel layouts (e.g., 3×5) eliminate need for landscape rotation
Long-press auto-spin replaces small, hard-to-tap toggle buttons
Bet sliders or gesture controls replace precision-targeted +/- icons

Battery life and data usage considerations

Extended slot sessions can drain your phone fast, so managing battery life and data usage for slot games is key. Most modern slots preload assets, but graphic-heavy animations still hog power. Lower your screen brightness and switch to low-data mode in settings to reduce strain on both battery and mobile plan.

Q: Do slot games use a lot of data while spinning?
A: Not usually—spins only send small signals, but bonus rounds with video sequences can chug your cap. Stick to Wi-Fi for those to save both battery and data.

Legal Landscape and Fair Play Standards

When you spin slots, the law demands provably fair randomness via certified RNGs (Random Number Generators). This means every outcome is independently audited and truly random, not rigged to make you lose faster. You can check a game’s RTP (Return to Player) percentage, which legally must match what’s advertised, giving you a factual baseline for your session’s potential value. Just remember that high RTP doesn’t guarantee frequent wins, though—it calculates long-term theoretical returns, not your immediate luck. Legitimate operators also enforce mandatory cool-down periods and loss limits you can set, turning fair-play standards into practical tools that protect your wallet from impulsive spins.

Licensing jurisdictions and regulatory bodies

slot games

When spinning slots online, the game’s fairness hinges on the licensing jurisdiction behind the casino. Reputable licensing bodies like the Malta Gaming Authority (MGA) or the UK Gambling Commission audit RNGs (Random Number Generators) to ensure outcomes are truly random and not rigged. Regulatory bodies also enforce payout percentages (RTP) and secure deposit safety. A license from Curaçao eGaming is common but has looser player-protection rules compared to the MGA. Always check a casino’s footer—if a trusted regulator’s name is missing, steer clear.

Audit protocols for RNG certification

Audit protocols for RNG certification in slot games require independent testing agencies to perform statistical analysis on at least several million spin cycles. These protocols verify that each symbol combination appears at its programmed frequency, ensuring no systemic deviation over time. The process involves certified random number generation validation using chi-square tests, serial correlation checks, and entropy measurement. A clear sequence governs this verification:

Review source code for algorithm integrity.
Execute hardware stress testing to detect drift.
Compare actual payout percentages against theoretical RTP.
Issue a timestamped certificate of compliance.

Only passing these strict protocols guarantees that slot outcomes remain provably unpredictable and unbiased for every player session.

Age verification and responsible gambling tools

Effective age verification for slot games requires robust identity checks, such as government ID submission or biometric liveness detection, ensuring no underage player can access real-money spins. Responsible gambling tools include customizable deposit limits, session timers, and cool-off periods that players can activate instantly from the game interface. Self-exclusion lists must be irreversible for a chosen duration, severing access to all slot titles without exception. These practical features allow users to maintain control over their play, with mandatory age gates and loss limits forming the first line of defense against harm within the game environment.

Emerging Trends in Interactive Entertainment

Emerging trends in interactive entertainment are redefining slot games by blending skill-based bonus rounds with traditional reel spins. Players now navigate mini-games using joystick controls or touch inputs, earning multipliers based on performance. Dynamic narrative progression systems unlock new reel sets as players complete objectives, while social features like live leaderboards and cooperative jackpot challenges foster real-time competition. Adaptive difficulty algorithms adjust volatility based on a player’s session history, ensuring personalized engagement. These trends shift slots from passive luck-based play toward active, participatory experiences.

Gamification elements like leveling and leaderboards

Leveling systems in slot games turn each spin into a progress bar, unlocking fresh themes or bonus rounds as you climb tiers. Leaderboards add friendly rivalry, showing your rank among players chasing the same jackpots. This social nudge often makes a losing session feel less frustrating when you see your name still climbing the chart. These gamified slot progression mechanics keep you engaged beyond mere payout hopes, rewarding consistency over luck. Unlockable avatars or milestones tied to your level give each session a tiny goal, while leaderboards reset weekly to keep competition fresh and accessible.

Crypto-based tournaments and provably fair algorithms

Crypto-based tournaments in slot games let you compete for prize pools using digital currencies, with wagers settled instantly on-chain. The real game-changer is provably fair algorithms, which let you verify each spin’s outcome directly via a hashed seed and client seed. You don’t have to trust the casino—just check the math yourself. In these tournaments, every entry and payout is logged on the blockchain, making results tamper-proof. Think of it as a transparent leaderboard where luck meets verifiable code. The nonce system ensures one spin can’t predict the next, keeping competition honest and fast-paced.

Virtual reality and augmented reality experiments

Developers are using immersive slot prototypes where VR headsets transport you inside a spinning reel chamber, letting you physically pull a lever floating in 3D space. AR experiments overlay bonus symbols onto your real-world table through a phone screen, triggering mini-games when you tap physical surfaces. These early builds prioritize gesture control over traditional buttons, but input lag remains a hurdle for fluid play.

Can I currently play a full slot session in VR without external sensors? Most demos still require a compatible headset and dedicated play area, though some mobile AR tests run on standard smartphones.

Tips for Choosing Your Next Reel Experience

When selecting your next slot game, prioritize volatility and RTP alignment with your playstyle. High-volatility reels offer sparse but massive payouts, ideal for patient hunters, while low-volatility slots provide frequent small wins for longer sessions. Always check the Return to Player percentage—anything above 96% is a solid benchmark. Next, explore the bonus features and mechanics that match your preference. Do you prefer cascading reels, expanding wilds, or interactive free-spin rounds? Preview the paytable and test the demo mode to ensure the betting range fits your bankroll without forcing risky bets. A focused choice based on these factors turns reels from random chance into an informed, engaging experience.

Reading paytables and understanding volatility labels

When selecting a slot game, first examine the paytable to identify each symbol’s payout value and any unique features like wilds or scatters, as this directly reveals win potential. Simultaneously, locate the volatility label, which indicates risk level: low volatility offers frequent but smaller wins, high volatility delivers larger but rarer payouts, and medium sits between. Matching volatility to your bankroll and playing style prevents frustration. For example, a paytable showing a high top prize and few mid-tier wins often signals high volatility.

Scan the paytable for symbol multipliers and bonus trigger conditions before betting.
Check the game’s info screen for explicit volatility tiers (low/medium/high).
Cross-reference the maximum win displayed against the hit frequency to confirm volatility.
Use the paytable to estimate Return to Player (RTP) combined with volatility for clearer expectations.

Testing demo versions before wagering real money

Before committing funds, testing demo versions provides a risk-free method to dissect a slot’s volatility and hit frequency. Analyze how often bonus rounds trigger during extended free spins, and note whether the base game sustains interest. This empirical approach reveals if the machine’s payout rhythm suits your bankroll strategy.

Use demo mode to calculate actual return-to-player variation over 200+ spins
Identify whether high-volatility paylines cluster during bonus cycles or random intervals
Validate that paytable values match claimed potential without financial exposure

Identifying trustworthy operators and software providers

To identify trustworthy operators and software providers for slot games, first verify providers’ game integrity by checking for independent audits from entities like eCOGRA. Analyze operator reputation through player reviews focused on payout speed and fair dispute resolution, avoiding vague testimonials. Scrutinize provider portfolios: established names like NetEnt or Microgaming consistently publish RTP (Return to Player) data, a direct indicator of transparency. Cross-reference operator partnerships with these providers, as unreliable operators rarely secure access to verified software. Prioritize operators offering detailed game descriptions and clear terms for bonus wagering.

Identifying trustworthy operators and software providers hinges on verifying independent audits, analyzing concrete player feedback on payouts, and cross-referencing partnerships with providers that publish transparent RTP data.
