Irish Snap
Irish Snap is a multiplayer card game using the standard deck of 52 playing cards where each player takes turns laying down one face up card each while counting. I.e. the first person says “ace” while laying down the first card; then the second person says “two” while laying down the next card. This process is repeated until the card that has just been laid down matches the number the person just called. When such a match happens, all players race to slap a hand on top of the pile of cards, and the slowest person has to take the pile into their hand. The first person to empty their hand wins.
