How it works

Ranks run from ace=1 to king=13. The same rank loses in this model. The gross multiplier equals (1−edge)/win probability; it includes return of the stake.

With replacement, a 7 has six ranks higher and six lower: each direction wins with probability 6/13.

Only the current card is known. Without replacement means a fresh shoe with that one card removed. No previous-card history, equal-rank wins, skips or operator rounding is included. An impossible direction has no payout.

P(higher) = 4d × (13−rank) / remaining; gross multiplier = (1−edge)/P
