About the game
Start with 100 virtual points. Predict whether the next number will be higher or lower, then draw. Independent draws mix numbers from 1 to 21 with jokers and three other special cards.
A correct prediction adds the drawn number times the joker multiplier. An equal number pays double and clears the mistake streak. Wrong predictions subtract the drawn number times the consecutive mistake count and multiplier.
Jokers boost the next numbered draw; the devil makes its next wrong prediction cost all points. A horseshoe doubles the score, a black cat halves it rounded up. Specials consume no numbered turn. Finish after 10, 20, 30, 40 or 50 numbered turns, or when points run out. Entertainment only: no real stakes or prizes. Points have no redeemable value and are not sold.
