Limbo calculator
Every Limbo target is a probability wearing a multiplier. This converts one into the other, and shows what the operator's margin costs you at that target.
A fair game would let you win 1 ÷ M of the time at a payout of M×. The house edge trims your win chance to (1 − edge) ÷ Mwhile keeping the same payout — that shortfall is the casino's margin. Higher targets pay more but win far less often.
The mathematics
Limbo is the simplest game in the category to analyse. Choose a target multiplier t, and a fair game pays t times your stake with probability 1 / t. Those two cancel exactly: stake × t × (1/t) returns your stake, which is what “fair” means.
The operator makes its money by paying a little under t for that same probability. The shortfall is the house edge, and because it is a fixed percentage of every bet, it applies just as surely at 1.01× as at 1,000×. Chasing a larger multiplier changes what your results look like, never what they are worth — see volatility in the glossary.

Questions
How is the win chance calculated?
For a target multiplier t, a fair game wins with probability 1/t. A 2× target wins half the time, a 100× target one time in a hundred. Operators apply their edge by paying slightly less than the fair multiplier for that probability, which is the difference the calculator makes visible.
Does a higher target multiplier improve my odds of profit?
No. Raising the target raises the payout and lowers the win chance by exactly the same factor, so the expected value is unchanged. What does change is variance: high targets mean long losing runs punctuated by rare large wins, which is a different experience with an identical long-run cost.
What's a typical house edge on Limbo?
Commonly around 1%, which is low by casino standards — but 1% of every bet, compounded across the turnover a fast game like this generates, is still a reliable negative expectation. A low edge slows the loss; it does not remove it.
Is Limbo provably fair?
At most operators offering it, yes — the result derives from a server seed, your client seed, and a nonce, so you can reproduce it afterwards with our verifier. That proves the number was not altered after your bet. It does not make the bet a good one.
Odds, not strategy.18+ only. No target multiplier has a positive expected value, and no sequence of bets changes that. This tool tells you the price of the risk, not how to win.
