Never bet more than 1–2% of your session bankroll on a single round. Crash games can produce long streaks of low multipliers; 10, 15 or even 20 consecutive rounds crashing below 1.5x are well within normal variance.
Different cash-out targets have different win rates. There is no mathematically superior target. Higher targets win less often but pay more when they hit.
Most crash games allow two simultaneous bets on the same round.
Chasing losses: after a losing streak the instinct is to increase your stake to recover. Don't. The next round has no memory of the last one.
Cashing out too early: micro-wins at 1.01x–1.1x erode your bankroll because occasional losses wipe out many small wins. Set a minimum target.
Ignoring session limits: decide your loss limit before you start, not during. UKGC-licensed sites are required to offer loss limits, so make sure you use them.
Playing without auto cash-out: manual cash-out requires fast reactions and emotional discipline. Most players do worse manually.
