Overview
Spit is a card game of the shedding family for two players. It is a form of competitive patience. The game is played until all of a player's cards are gone. It has a close variant known as Speed. Spit appears to have originated in the UK in the 1980s.
Objective
The goal of Spit is to get rid of one's cards as quickly as possible. The players do not take turns; physical speed and alertness is required to play faster than the opponent. On each deal, the player who is first to go through all of their starting cards can reduce the number of cards for the next deal. By being successful for several deals, clearing all of one's cards becomes possible, and if this is carried out successfully, one wins the game.
Setup
Spit is played by two players. The entire pack is split between them, and each player makes five stacks in front of themselves in a row as follows:
Stack 1: (0 cards face down), 1 card face up
Stack 2: 1 card face down, 1 card face up
Stack 3: 2 cards face down, 1 card face up
Stack 4: 3 cards face down, 1 card face up
Stack 5: 4 cards face down, 1 card face up
