Towers calculators
For Towers, a target multiplier is the ladder value you hold when you cash out, so the first calculator shows the chance that one climb, under this site's fixed mix of difficulty levels and stopping floors, pays at least that much. The second applies the 5% house edge to your stake and number of rounds, and the third estimates the chance of a losing streak and what a doubling system would lose by its end. Targets above the 3,840x cap cannot be reached.

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.

Expected return
95.00
The house edge is 5.0% of every unit staked, so 100 rounds at 1.00 cost 5.00 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.

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 100.0%. A system that starts at 1 unit and doubles after every miss has lost 255 units by the end of that run.
