Limbo

Set your target multiplier. A random number is rolled. If it’s above your target, you win that multiplier × your bet. 1% house edge — one of the lowest in any casino.

2.00×your target — set it then roll

Math · how Limbo’s house edge works

Distribution	P(rolled ≥ x) = 0.99/x for x ≥ 1.01
Pick 2× target	49.5% win chance · pays 2× = expected return 99%
Pick 10× target	9.9% win chance · pays 10× = expected return 99%
Pick 100× target	0.99% win chance · pays 100× = expected return 99%
The expected return is constant 99% regardless of your target. The house edge is fixed at 1% — same as best-case blackjack with no skill required.
