Aviatrix calculators
All three calculators work from Aviatrix's published 97% RTP, a 3% edge at every target. The game tops out at 10,000x, but casinos usually cap the cash a single bet can win, so for realistic targets the chance of reaching them matters far more than the ceiling. If you play both bet panels, count each one as a separate bet in the cost and streak tools.

Chance of at least one 10.00x within 20 rounds: 87.0%.
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
100.00
Expected loss
3.00
Expected return
97.00
The house edge is 3.0% of every unit staked, so 100 rounds at 1.00 cost 3.00 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.
Miss chance per round
51.5%
Chance of at least one such run
37.8%
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 37.8%. 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 97% and the same model as the methodology page. They show long-run averages and probabilities, not predictions. RTP & Fairness · Methodology
