Short explanation
How casino bonus rollover works
Rollover is a wagering target. It describes how much qualifying play is usually required before bonus-related money can be withdrawn.

€3,500 wagering target The target is the amount of qualifying bets, not the amount you need to win.
What to observe
What the simulator can show you
Try changing one term at a time and compare how the simulation feels.
Losing bets can still count
A qualifying spin can move wagering progress forward even when the balance goes down.
Completing rollover is not profit
Reaching the target does not guarantee that the final balance is higher than the starting balance.
Bet size changes the journey
Larger bets move progress faster, but they can also reduce the balance faster.
Rollover size matters
A higher multiplier creates a larger wagering target and usually takes longer to complete.
Conversion limits matter
A max conversion rule can limit how much bonus value becomes withdrawable cash.

Simulator questions
Casino simulator FAQs
Does this simulator use real money?
No. Every balance, spin, win, and result is simulated for educational purposes.
Are the simulated results predictions?
No. They are examples designed to demonstrate the relationship between betting activity, balance changes, and rollover progress.
Why does a losing spin increase rollover progress?
The simulator counts the qualifying bet amount toward progress. Whether the spin wins or loses is a separate result.
Does every real casino game count equally?
No. Real promotions can assign different contribution percentages or exclude some games entirely.
