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.
| 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. | |
Limbo is a recent online-casino invention: pick a target multiplier (say, 5.0x). The game generates a random multiplier. If your target is below the generated value, you win at your target's multiplier; if above, you lose. Mathematically nearly identical to crash, with a clean 1% house edge in most implementations.
Choose a target multiplier between 1.01x and a maximum (often 1,000,000x). The site generates a random multiplier from a distribution calibrated so that betting "above" a chosen target X has probability 0.99 / X. Win the chosen multiplier on success; lose your bet on failure.
Like crash, every target has identical EV (-1%) — the only choice is variance. Higher targets mean rarer wins and bigger payouts. There is no "right" multiplier; it's a personal preference between frequent small wins and rare big hits. Provably-fair implementations let you verify the random value was generated before you placed your bet via hash commitments.
For target X and house edge h, P(win) = (1 − h) / X. EV = X × P(win) − 1 = (1 − h) − 1 = −h. With h = 0.01, expected loss is 1% per bet regardless of target. Variance scales as approximately X — a 100x target has 100× the variance of a 2x target.
Limbo emerged in 2019 on Stake.com and similar crypto-first casinos. It is essentially crash without the visualization — purely a number-out-of-distribution bet.
