How to play

Each level, everyone is dealt the same number of secret cards numbered 1 to 100 (level 1: one card, level 2: two cards, and so on). Together you must play every card in ascending order, with no talking, gestures or hints. There are no turns: when you feel your lowest card is next, play it.

If someone plays a card while another player holds a lower one, the level is lost: everyone sees the cards that were held, and the same level starts over with a fresh deal. There are no lives, so keep trying until you clear it, then move up a level.
