RTP (return to player) is the share of all money staked on a game that it pays back over a very large number of rounds. A 97% RTP game returns $97 for every $100 wagered on average, and keeps $3 as the house edge. The ten games below have some of the highest published RTPs you will find at mobile casinos: five slots, three crash games and two instant games.
A higher RTP lowers the average cost of playing. It does not tell you how often a game pays or how large the wins are; that is volatility. Read our guide to RTP at mobile casinos for the full picture, and the house edge guide for how RTP turns into cost.
A published RTP is the studio's figure for one build of the game. The same title can ship in more than one build, and the casino chooses which build to load. The figure in the info screen is the one that applies to the bets you place in that session. Use the table on this page as the studio's top published figure, then confirm it in the game before you raise the stake.
RTP and house edge are the same split, written two ways. A game that returns 97% keeps 3% as the house edge. That edge is an average across a very large number of rounds, not a fee taken from each spin. A short session on a phone can finish well above the RTP or well below it. The average only settles after far more rounds than one sitting covers.
The 10 games at a glance
RTPs are the figures the studios publish for each game. Some studios supply casinos with more than one RTP version of the same game, so check the figure in the game's info or help screen before you play. On a phone, that screen is usually behind the "i" or menu icon.
| Game | Studio | Type | RTP | Volatility |
|---|---|---|---|---|
| 1. Ugga Bugga | Playtech | Slot | 99.07% | Low |
| 2. Mega Joker | NetEnt | Slot | 99% | High |
| 3. Book of 99 | Relax Gaming | Slot | 99% | High |
| 4. 1429 Uncharted Seas | Thunderkick | Slot | 98.6% | Not stated |
| 5. Blood Suckers | NetEnt | Slot | 98% | Medium |
| 6. Aviator | Spribe | Crash game | 97% | Medium |
| 7. Spaceman | Pragmatic Play | Crash game | 96.6% | Medium |
| 8. Pine of Plinko | Print Studios | Instant game | 96.5% | High |
| 9. Big Bass Crash | Pragmatic Play | Crash game | 96.5% | High |
| 10. Mines Dare to Win | Hacksaw Gaming | Instant game | 96% | Medium |
The table orders the ten games by the studio's published RTP, from Ugga Bugga at 99.07% down to Mines Dare to Win at 96%. Studio, type and volatility sit beside the figure so you can compare games of the same kind. A blank volatility cell means the studio has not stated a rating in the data this page uses. The order is not a ranking of which game you should play, and it is not a forecast of your next session.
1. Ugga Bugga: 99.07% RTP
Playtech publishes a 99.07% RTP for Ugga Bugga, the highest on this list. Ugga Bugga is not a standard five-reel slot. You can hold symbols in place between spins and respin the rest, which gives you a decision to make on each round.
It is a low-volatility game, so wins come often and tend to be small. The tribal theme and simple layout keep the screen readable on a phone. Check the help screen for how the hold feature works before you stake real money.
Ugga Bugga lets you hold symbols between spins and respin the rest. Holding a symbol keeps it for the next spin and gives up the chance to change it. That choice changes which lines can complete. It does not change the published RTP, because the figure already includes rounds where players hold and rounds where they respin.
2. Mega Joker: 99% RTP
Mega Joker by NetEnt is a classic fruit machine with a published RTP of 99%. It uses two sets of reels: wins from the lower game can be moved up to the Supermeter mode, where you play at higher stakes for larger prizes. The game also carries a progressive jackpot.
It has 3 reels and 5 paylines, and NetEnt rates it high volatility. Expect long runs without a win between larger payouts, and keep the stake at a level you can hold through them.
Mega Joker's Supermeter is a second set of reels that you fund with wins from the lower game. Moving a win up raises the stake for the next stage and can pay a larger prize, including the progressive jackpot. Leaving the win in the lower game keeps the stake smaller. Either choice is already inside the 99% RTP.
3. Book of 99: 99% RTP
Book of 99 by Relax Gaming has a published RTP of 99%. It is a 5-reel, 10-payline slot rated high volatility. It follows the "Book of" format: scatter symbols trigger free spins, and an expanding symbol in the bonus round covers whole reels.
The free spins round is where most of the game's return sits, so base-game spins can feel quiet. That is normal for a high-volatility slot.
Book of 99 puts most of its return in the free-spins round, where one expanding symbol covers whole reels. Scatter symbols are what start that round. Base-game spins can pass with no feature and still be consistent with a 99% RTP, because the average includes the rounds that do trigger the book.
4. 1429 Uncharted Seas: 98.6% RTP
Thunderkick publishes a 98.6% RTP for 1429 Uncharted Seas. The slot has a nautical theme with an old sea-chart look, and the artwork scales well to a phone screen.
Thunderkick does not list a volatility rating for it in our data, so try it in demo mode first to see how often it pays at your stake.
1429 Uncharted Seas is a standard reel slot with a sea-chart theme that stays readable on a small screen. Thunderkick publishes 98.6% for it and does not state a volatility rating in the data used here.
5. Blood Suckers: 98% RTP
Blood Suckers by NetEnt is a vampire-themed slot with a published RTP of 98%. It has 5 reels and 25 paylines and is rated medium volatility.
There are two bonus features: free spins with multiplied wins, and a pick-and-win bonus game where you choose coffins to reveal prizes. Medium volatility makes it a steadier choice than Mega Joker or Book of 99.
Blood Suckers splits its features between free spins, which multiply wins, and a pick-and-win round where you open coffins for prizes. Both features are part of the 98% RTP, not an extra on top of it.
6. Aviator: 97% RTP
Aviator by Spribe has a published RTP of 97%, the highest of the three crash games here. A plane takes off and a multiplier climbs. You cash out before the plane flies away to win your stake times the multiplier; if it leaves first, you lose the stake.
You can place two bets on the same round and set auto bet and auto cashout for each, which suits one-handed play on a phone. A live panel shows other players' bets and cashouts, and there is an in-game chat. Spribe released it in 2018 and rates it medium volatility.
Spribe's published RTP for Aviator is 97%%. Spribe released Aviator in 2,018 and rates the game medium volatility. The published RTP is an average over a very large number of rounds, and a single flight can end below it. Cashing out early locks a smaller multiplier. Waiting for a higher multiplier raises the chance the plane leaves first and the stake is lost.
7. Spaceman: 96.6% RTP
Spaceman by Pragmatic Play is a crash game with a published RTP of 96.6%. A spaceman flies off as the multiplier rises, and you cash out before he drops out of the round. It came out in 2023 and is rated medium volatility.
Spaceman has auto cashout, so you can set a target multiplier before the round and let the game pay out when it gets there. That removes the need to tap at the right moment on a small screen.
Pragmatic Play publishes an RTP of 96.6%% for Spaceman. Spaceman came out in 2,023 and is rated medium volatility. The round ends when the spaceman drops, and any bet still open at that moment loses. A target set with auto cashout is filled when the multiplier reaches it, and it is ignored if the round ends first.
8. Pine of Plinko: 96.5% RTP
Pine of Plinko by Print Studios is an instant game with a published RTP of 96.5%. It takes the Plinko idea, a ball dropping through a board of pegs into prize slots at the bottom, and adds a pine-forest theme. Print Studios rates it high volatility.
Each drop is decided by chance, not by your timing or aim. Our Plinko guide explains how the board and the payouts work.
Print Studios publishes an RTP of 96.5%% for Pine of Plinko and rates it high volatility. Each drop is one independent draw. The pegs send the ball into a prize slot, and the slot's multiplier is the result. Your timing and aim do not move the ball. The published RTP already averages the small slots and the rare larger ones.
9. Big Bass Crash: 96.5% RTP
Big Bass Crash by Pragmatic Play brings the Big Bass fishing theme to a crash game, with a published RTP of 96.5%. It follows the standard crash format: a multiplier rises, and you cash out before the round ends to keep your winnings. It came out in 2023 and is rated high volatility, unlike Aviator and Spaceman.
Auto cashout and a live list of other players' bets are part of the game, as in most crash titles. You will find it at many mobile casinos, including the ones in our list of high-RTP games on 1xBet.
Pragmatic Play publishes an RTP of 96.5%% for Big Bass Crash. The game came out in 2,023 and is rated high volatility. The fishing theme does not change the crash rule: the multiplier climbs until the round ends, and an open bet loses if you have not cashed out. Auto cashout still applies the target you set before the round starts.
10. Mines Dare to Win: 96% RTP
Mines Dare to Win by Hacksaw Gaming is an instant game with a published RTP of 96%. It plays like Minesweeper: you uncover tiles on a grid, each safe tile raises your prize, and hitting a mine ends the round and loses the stake. You can cash out after any safe tile.
Where the mines sit is random, so no picking pattern improves your odds. What you control is how many tiles you open before cashing out, which sets how much a round can win or lose. Hacksaw rates it medium volatility, and stakes run from $0.20 to $100 per round. See our Mines guide for the rules.
Hacksaw Gaming publishes an RTP of 96%% for Mines Dare to Win and rates it medium volatility. Each safe tile raises the prize and each mine ends the round. The mine positions are drawn before you pick, so a pattern of tiles does not improve the chance a tile is safe. Opening more tiles raises the prize and also raises the chance the next tile is a mine.
How volatility changes what an RTP means in practice
Volatility describes how a game spreads its return across wins. A low-volatility slot pays small wins often, so a session tends to move slowly around the starting balance. A high-volatility slot pays less often, and its larger wins arrive in bursts. Both kinds can carry the same RTP, which is why the published figure alone does not describe the experience.
The RTP is calculated over a very large number of rounds, and variance decides how far a single session can drift from that average. A player with a small balance can run out before a high-volatility game reaches its typical return, even when the RTP is high. A player with a larger balance has more room to wait for a feature to land.
Volatility also affects how you should size stakes. A common approach is to pick a bet size that gives the balance enough spins to reach the bonus or feature round. On a phone, where sessions are often short, this matters more than on a desktop, because the session ends before the average has time to show.
Studios rate volatility differently, and some do not publish a rating at all. The table above shows the rating where the data provides one. Treat that column as a guide to pacing, not as a measure of the RTP. Two games with the same rating can still feel different because the feature set and hit frequency differ.
Crash games are a separate case. Each round ends at a random point, and the player chooses when to cash out. The game design fixes the RTP, but the cash-out rule decides how the return is spread across many rounds. Crash games therefore reward a clear cash-out rule more than a feeling about the next round.
Using RTP when you play with bonus money
Bonus money usually carries conditions that the RTP does not cover. A casino can restrict which games count toward wagering, and many casinos weight slots and crash games differently. Check the bonus terms before you pick a game for bonus play, because a game with a high RTP can still contribute only part of each stake toward the requirement.
A high RTP helps most when the stake is your own money and the session is long enough for the average to matter. Bonus play adds a second layer, because the conversion of bonus funds into cash depends on the terms, not only on the game. The wagering requirements guide explains how that conversion works, so read it before you start.
Players who already know the basics often look for games that suit their stake and session length. Games chosen for strategy and variance need a different way of reading the RTP table. The list for advanced players covers those games and is a better next step once volatility is clear.
What the RTP table does not show
The table on this page lists one published figure per game, and that figure can change. Studios release new builds, and a casino can run an older build for a period, so the number on the page may not match the version in your app. The information screen inside the game is the most direct check.
The table also leaves out the bet range. A game can publish a high RTP at one stake and offer a different set of paylines or features at another. Read the minimum and maximum stake in the game before you commit a session budget to it.
Hit frequency is a separate measure that the RTP does not show. Two slots with the same RTP can land a win in very different numbers of spins. Hit frequency shows how often the game pays, volatility shows how the wins are sized, and the RTP shows the long-run average across both.
Read the game's own rules page as well as its RTP figure. Some games list a feature-buy price or a maximum win that changes how the RTP behaves at high stakes, and the published rules explain how those terms apply. A figure without its rules tells you the average, but not the conditions under which the average was measured.
A single figure cannot predict a session. Your balance, stake size and number of rounds shape the result far more than a small gap between two published RTPs. The RTP is most useful as a tie-breaker between games you already like.
How to use RTP when you pick a game
- Compare RTPs within a game type. Among the slots here, Ugga Bugga, Mega Joker and Book of 99 sit at 99% or above. Among the crash games, Aviator has the highest figure.
- Check the version. The RTP in the game's help screen is the one that applies at that casino. If it is lower than the studio's top figure, the casino runs a lower-RTP version.
- Match volatility to your budget. Low-volatility games such as Ugga Bugga pay small amounts often. High-volatility games such as Mega Joker, Book of 99 and Big Bass Crash can go many rounds without a win.
- Remember the time scale. RTP is measured over millions of rounds. A single session on your phone can end well above or well below it.
Fast games such as crash and Mines let you place many bets in a few minutes, which adds up the house edge quickly. Set a budget before you start and use your casino's deposit limits; our responsible gaming page lists the tools. For more on the game types, see our guides to mobile slots, crash games and instant games.
A fast game spends the house edge sooner because you finish more rounds per minute. Crash rounds and Mines tiles can stack dozens of bets in the time one slot bonus takes to play out. The RTP percentage stays the same. The money it describes moves faster. A session limit and a loss limit, set in the casino before you open the game, cap that speed.
When two games share an RTP, the version in the info screen is the tie-break. If the screen shows a lower figure than the studio's top number in the table, that casino runs a lower-RTP build. Play the build you checked, rather than assuming the table's figure transferred.
