A game of speed, challenge, and intellect? (or was that Thumper?) Anyways, a good game with a Very High buzz factor. Supplies: people, beer, and cards.
Best played with a large number of people (for obvious reasons). One person is designated as the dealer. (This person should be changed every round because the dealer is at a distinct disadvantage. Some people play that the dealer does not play on his/her turn.) The dealer begins by placing cards, face up, in a stack, and calls out the number on each turn.
