RTP and volatility are two of the most important figures on any slot, but they measure completely different things, and confusing them is a common mistake among new players. If you are in the same situation, don’t worry. We will show you how the two interact and how to use both together when choosing a game.
Quick Recap — What Each One Measures
RTP, or return to player, is the percentage of all money wagered that a slot returns to players over millions of spins. A 96% RTP means that, theoretically, about €96 returned for every €100 staked on average, over a very long period. You can read our full RTP guide here.
Volatility, also called variance, describes how a slot distributes those returns. High volatility means infrequent but larger wins, while low volatility means frequent but smaller wins, with medium volatility sitting between the two. Find our full slot variance guide here.
The key distinction is simple: RTP is about the total amount returned, while volatility is about the pattern and size of the wins.
Why You Cannot Judge a Slot by RTP Alone
Two slots can share the same RTP and still play completely differently. Slot A, with a 96% RTP and low volatility, pays small amounts often and rarely goes long without a win. Slot B, also with a 96% RTP but high volatility, could go 200 or more spins without a meaningful win, then deliver one large payout.
Over a sufficiently large number of spins, both should trend towards the same 96%, yet the session experience is entirely different. One slot can be steady and gentle on your bankroll, while the other may keep you waiting longer for those rare, bigger wins.
The Four Common Combinations
Putting the two metrics together gives four broad combinations, each with a different feel in practice. The examples below are titles available in the TonyBet Ireland casino:
| Combination | What it feels like | Example on TonyBet |
| High RTP + Low volatility | Frequent small wins; suitable for longer sessions on a limited budget | Starburst (96% RTP) |
| High RTP + High volatility | Strong long-term return, but needs patience and a larger bankroll during dry spells | Wanted Dead or a Wild (96.38% RTP) |
| Low RTP + Low volatility | Regular small wins, but a higher house edge; less value over time | RIP City (can be configured to run at 96.22%, 94.27%, 92.32%, 88.02%) |
| Low RTP + High volatility | Infrequent wins and a higher house edge; the most demanding mix | Gates of Olympus 1000 |
High RTP, low-volatility slots are generally gentler on a bankroll, and Starburst by NetEnt is the classic example. It pays out often, which can help stretch a session, making low-volatility slots like this a common starting point for newer players.
Wanted Dead or Wild by Hacksaw has a high-RTP, high-volatility profile, with the potential for long quiet spells before a big hit, and the classic version of Gates of Olympus by Pragmatic Play behaves similarly.
Low-RTP games are best approached with caution, as a higher house edge works against value, even when wins are spread more evenly.
Which Combination Is Right for You?
There is no single best combination, only the one that fits how you like to play, and none changes the odds in your favour. Use the two figures as a guide to finding a game that suits you, rather than a strategy for winning.
If you have a limited budget or want a shorter, steadier session, lean towards lower volatility so your stake lasts longer. If you are comfortable riding out dry spells for the chance of a bigger moment, higher volatility may suit you better.
If value is your main concern, prioritise the best high-RTP figure you can find, regardless of volatility. Remember that RTP is a long-term average measured over millions of spins, so no combination guarantees a profitable session or even a winning one.
Where to Find RTP and Volatility on TonyBet
Most slots show their RTP in the game information or paytable section, usually reachable from a menu or an “i” icon inside the game. Volatility is sometimes listed there too, labelled as variance or shown as a visual indicator, though not every game displays it.
As a reliable cross-check, provider websites such as Pragmatic Play, NetEnt, and Play’n GO publish certified RTP figures for each game.
