Set your bet amount and automation
Before each round you set your bet amount. Starting small is sensible, because rounds end very quickly and it is not always possible to cash out in time by hand.
That is why the auto cash-out feature matters. You choose a multiplier in advance — such as 2.0x. As soon as the multiplier reaches that level, the game exits on its own and you do not need to watch the screen.
The auto play setting lets you run multiple rounds in a row with the same bet amount. However, you should not take your eyes off the screen while auto play is running — the situation can change at any moment.
Many players place two bets at once: one with auto cash-out set at a low multiplier (such as 1.5x) and another held manually in hopes of a higher multiplier. This way one bet gives a near-certain return while the other keeps open the chance of a larger payout.
