ABOUT SPEED
Speed (also known as Spit) is a classic two-player card game. A 52-card deck is split evenly. Both players play simultaneously onto shared centre piles. Any card one rank above or below the top card is legal. Aces wrap between King and 2. When neither player can move, flip a new card onto each pile to unblock. First to empty their entire hand and stock wins.
Play anytime, anywhere. Matches take under three minutes.
