Limbo
Pick a target multiplier; an instant number rockets up. Beat it and you win the target; miss and it's gone. The fast, one-tap, single-player cousin of crash.

Aim high. Launch. Beat it.
Set your target
Choose the multiplier you're chasing — the win chance and payout update live. Higher target, bigger payout, longer odds.
Instant launch
A number rockets up to a provably-fair generated multiplier. Land at or above your target and you win.
Verify it yourself
The generated multiplier is recomputable from the revealed seed.
Verifiable every play.
The generated multiplier comes from one HMAC draw over a committed server seed (the same distribution as a crash point), revealed after each play for verification.
