Crash games show a multiplier that climbs from 1.00x and can stop ("crash") at any second. You bet before the round and cash out before it crashes to keep your multiplier.
A simple plan
Decide a target multiplier and use auto-cashout so emotion does not take over. Many players bank a small, safe multiplier most rounds and occasionally let one run. The crash point is provably random, so there is no pattern to chase. Set a session budget and stop when you hit it.
