Ten thousand sessions replayed

What your budget can return: the simulator

"Can it pay?" is the question everyone asks and nobody answers with numbers. The simulator replays your session 10,000 times using Monte Carlo, from the real RTP and volatility of the chosen slot, and shows you the full distribution of outcomes. Not a prediction: a picture of what the probabilities look like.

What it computes, and from what

You pick a slot, a budget, a stake, and a mode: normal spins or bonus buy. The engine then draws 10,000 complete sessions from three real inputs: the slot's RTP, its volatility, and for bonus buys its price as read in-game.

That last point is what sets it apart from every generic calculator: the buy price is not estimated, it is read slot by slot on 909 of them. A simulator assuming "100x" everywhere gives wrong answers the moment a game costs 60x or 500x.

What the distribution shows that an average hides

Saying a slot returns 96% says almost nothing about your session. Across 10,000 identical sessions, a good share end at zero, a good share end slightly below budget, and a small fraction far above. The average is the one value almost nobody gets. That is precisely what the chart makes visible.

This is where volatility finally makes sense without jargon: at equal RTP, a low-volatility slot gives a tight cloud around your budget, a high-volatility one gives many zeros and a few peaks. The word stops being a label and becomes a shape.

What it is for before you stake

Calibrating your stake. The same budget at half the stake doubles the number of spins and completely changes the shape of the distribution.
Knowing whether a bonus buy is within reach. A 100x buy on a €50 budget leaves no second attempt: the simulator shows that immediately.
Picking volatility to match your goal. Lasting long and chasing a big hit do not call for the same slot, and it is not a matter of taste but of curve shape.
Comparing two slots with identical RTP. The most useful case, because RTP alone never separates them.

What the simulator does not do: it does not predict your next result. Every spin stays independent. It describes probabilities from measured data, which is already far more than a lone stated RTP figure.

To pick the slot to simulate, the ranking of 1,705 slots by verified RTP shows which ones hold their stated figure. And if you are preparing a buying session, the bonus hunt tracker takes over once you play.

Frequently asked questions

How much can you win on slots?

There is no single answer: there is a distribution. For a given budget and stake, the simulator replays 10,000 sessions from the slot's real RTP and volatility and shows how outcomes spread out, from zero to the top, rather than an average almost nobody gets.

Does the simulator predict my winnings?

No, and that distinction matters. It describes probabilities from measured data. Each spin stays independent of the last: no tool can say what is coming.

What data does the simulator use?

The slot's RTP, its volatility, and for bonus buy mode the real buy price, read in-game on 909 slots. That last point sets it apart from generic calculators that assume one identical price everywhere.

What does a slot's volatility do?

At identical RTP, it decides the shape of the outcomes. Low volatility gives many small wins and a session that lasts; high volatility gives long dry runs and a few big hits. The simulator makes that difference visible at a glance.
