Fast and Fun Number Crunch’n! It’s as easy as 1, 2, 3! Players add, or subtract, 1, 2, or 3 to the number on the top card on the pile to determine if they have a card that can be played next. Sounds simple, but with everyone playing simultaneously, the options are constantly changing. The first player out of cards wins! Achtung: Nicht für Kinder unter 36 Monaten geeignet.
