Each mode has its own published math.
- ModePublished RTP
Each game defines its own modes, such as base play, ante or a bonus buy. The same name can work differently in another game.
Mode costThe theoretical long-run return for this mode, as a share of what one round costs. It does not predict a single session.
Max winThe price of one round in this mode, in base bets. 100x bet means 100 times your base bet.
Max win chanceThe biggest payout in this mode’s published math, in base bets. It is not a multiple of the mode cost.
Published outcomesHow often the max win comes up per round in this mode, from the published math. Recent results don’t change it.
How many outcomes this mode’s published math lists. Some have zero chance. This is not a count of player spins.
