Aim high, climb higher · Provably fair
Pick a target multiplier, then watch the number climb. If it reaches your target before it stops, you win your bet times the target. Aim at 2× and about half the rounds get there; aim at 100× and hardly any do, but each one pays a lot.
Set the target on the gauge: drag the gold tag (it snaps to 1.5×, 2×, 3×, 5×, 10× and so on), tap its arrows to step it, or tap its middle to type one, from 1.01× to 1,000×. The higher the target, the smaller the chance, and every setting returns the same 97%. Auto plays as many rounds as you like at your target, with a stop at a profit or a loss.
Every round comes from your own provably fair seed pair the moment your bet is placed, never before. Check any one on the Provably fair page.
