- Press the "Cash Out" button before the "crash" — the profit is yours.
- If you do not cash out before the crash, you lose that round's bet.
Auto Cash Out: You can set an automatic cash out at a specific multiplier. Set your stop limit before the game starts — this is important for responsible gaming.
There is no guarantee of winning or any "signal" in crash games. Every round is completely independent. Play responsibly.
