Put up a stake (max 25) and climb 4 rungs: 1) red or black, 2) higher or lower than card 1 (tie loses), 3) inside or outside cards 1 & 2 (tie loses), 4) the exact suit. Clear a rung and CASH OUT at its multiplier — 2x → 3x → 5x → 10x — or press on. One wrong guess and the House keeps your stake. Ties screw you. 5 rides per day. One real 52-card deck per day — cards you've seen are gone. Memory is a strategy.
