Lucky Jet calculators
These calculators use Lucky Jet's published 97% RTP, a 3% house edge on every bet, including each of the two bets you can place in a round. 1win publishes no top multiplier, so targets stop at 10,000x, the cap this site's model assumes; the largest win recorded in game databases is 5,072x.

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
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.

How likely is a run of misses at your target? Worth checking before trying any doubling system.

Units a doubling system loses

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
