Game modes · v1

Each mode has its own published math.

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