Life pool was a form of pocket billiards (pool) mainly played in the 19th century. It was one of several pool games that were popular at this time (so called because gamblers pooled their bets at the start of play). The object of the game was to be the last player left "alive" and therefore scoop the pool (take the winnings). Each player had three "lives" to begin with and would lose one when another player potted their coloured ball which was designated to them at the start of the game.[clarification needed] Once a player lost their three lives, they were declared "dead", i.e. out of the game. The game continued in this way until there was only one player left, who was declared the winner. Around 1875, life pool merged with black pool to form the new game of snooker, today one of the most popular cue sports in the world.
