Overview
Speed is a game for two players of the shedding family of card games, in which players try to get rid of all of their cards first. It is a form of competitive patience similar to Spit.
How to deal
Each player is dealt five cards to form a hand and 15 cards face down to the side as a draw pile.
Play
With two players, the round begins when the players flip one of the face-down cards in the centre simultaneously. Players must then discard their hand cards one by one, using only one hand, matching cards so that each card played is either one number above, one number below, or the same number as the two cards on top of the center stacks. This must be done without hesitating to shuffle cards or otherwise delay the game. Only one card can be placed at a time. The ace and king can be placed on top of one another, forming a looping sequence. Whenever the number of cards in a player's hand drops below five, the player has to take more cards from the draw pile to bring it back up to five cards until the draw pile is depleted. When players run out of options for play they simultaneously flip a card from the side piles onto the top of the central piles. If these piles become depleted, the central stacks are shuffled individually and are placed face-down as new side piles from which cards can be flipped.
The first player to run out of cards says "Speed" and is then the winner. The overall winner is decided by the best of three games. If a player has a card to place it must be placed.
