Big Bass Crash calculators
Big Bass Crash publishes an RTP of about 95.5%, so every target carries a 4.5% house edge, a little more than games paying 97%. Rounds stop and pay at 5,000x, which means no target above that can be reached. The calculators below show how rare a given target is, what 4.5% costs over a session at your stake, and how fast a doubling system runs into the stake limit after a few early snaps.

Session cost calculator
The house edge applies to every unit you stake. This is the long-run average; a single session can end far above or below it.
Total staked

4.50
Expected return
95.50
The house edge is 4.5% of every unit staked, so 100 rounds at 1.00 cost 4.50 on average. Winning rounds do not reduce this: the edge applies to the total you put through the game.
Losing-streak calculator
How likely is a run of misses at your target? Worth checking before trying any doubling system.
Miss chance per round
52.3%
Chance of at least one such run
40.9%
Units a doubling system loses
255
Aiming for 2.00x, the chance of 8 misses in a row at least once in 200 rounds is 40.9%. A system that starts at 1 unit and doubles after every miss has lost 255 units by the end of that run.
Every calculator uses the published RTP of 95.5% and the same model as the methodology page. They show long-run averages and probabilities, not predictions. RTP & Fairness · Methodology
