What the offer simulator shows

The simulator starts with your deposit plus the bonus, then spins a simple slot model until the wagering is complete or the money runs out. It repeats that 2,000 times and shows how often you’d finish with something to withdraw, and how much.

It’s a model, not a real game, but it shows something averages hide: with high volatility, most plays run out of money while a few finish well ahead. With low volatility, results bunch closer to the average.

Questions

Is this how real slots work?

Real slots have far more outcomes, but the model uses the same RTP and a similar spread of wins, so the overall pattern is realistic.

Can I use this to beat a bonus?

No. On average you still pay the house edge on every spin. The simulator just shows the range of likely outcomes.
