Slot volatility: what it is and how to read a game page
Every game page on IPU.BET shows several figures: provider RTP, volatility, online RTP, win chance and maximum win. Here is what they mean and what not to expect from them.
What a game page shows
- Provider RTP: the declared return over a very long run.
- Volatility: how wins are spread, frequent and small or rare and large.
- Online RTP: the actual return of the game over the last 24 hours.
- Win chance: an IPU.BET estimate based on the game's data.
- Maximum win: the ceiling per bet, if the provider or the catalogue lists one.
RTP: a long run average, not a promise
An RTP of 96% means that over millions of spins the game returns 96% of stakes on average. In a single session the result can be anything, including far lower. On top of that, one game can come in several RTP variants, and the casino picks which one to run. See our article on why the RTP of one slot differs between casinos.
Volatility: how wins are spread
With low volatility, wins come often but are usually small. With high volatility, there can be long runs without notable wins, and big amounts sit in bonuses and rare combinations. Such games can have almost the same RTP: volatility changes the size of the swings, not the average.
| Game | Provider RTP | Volatility | Maximum win |
|---|---|---|---|
| Wild Hot 40 (Fazi) | 96.58% | low | not listed |
| Wolf Gold (Pragmatic Play) | 96.01% | medium | 2,500x bet |
| Big Bass Bonanza (Pragmatic Play) | 96.71% | high | 2,100x bet |
| Sweet Bonanza (Pragmatic Play) | 96.51% | high | 21,175x bet |

Online RTP for 24 hours: how to read it
It is the actual return of the game over a short window. It can be well above or below the declared figure: in one day a game goes through too few spins to reach its average. It is interesting statistics, not a sign that the game is "paying now".
How to choose a game for your budget
- Set your session budget in advance and do not raise it while playing.
- With high volatility, a run without wins can be long: keep that in mind when choosing your stake.
- If you want to play longer on the same budget, look at low or medium volatility games.
- No strategy changes RTP or volatility: every spin is random.

FAQ
What is slot volatility?
It describes how wins are spread: frequent and small with low volatility, rare and large with high volatility.
Does high volatility mean winning is easier?
No. It means rarer but bigger wins and longer runs without them. The average return is set by RTP, not volatility.
What is online RTP on IPU.BET?
The actual return of the game over the last 24 hours. The window is short, so the figure can differ a lot from the declared RTP.
Can you tell when a slot is "paying"?
No. Every spin is independent and decided by a random number generator.
