Irish Switch, also called Two-four Jacks, Lives or Black Jack, is a version of the card game Switch popular in Ireland. It is very similar to the original with a few rule changes. Switch is a shedding-type card game for two or more players that is popular in the United Kingdom, and as alternative incarnations in other regions. The sole aim of switch is to discard all of the cards in one's hand; the first player to play the final held card, and ergo have no cards left, wins the game. Switch is very similar to the games Uno and Mau Mau, both belonging to the larger Crazy Eights family of shedding games.
