Knowledge
About Speed
Speed is a two-player card game where both players play simultaneously. Using 52 cards (excluding jokers) divided equally into red and black suits, players must play cards one rank higher or lower than the two field cards in the middle.
Local rule variations
Speed has different rules depending on region or playgroup—notably whether King and Ace connect, and whether jokers are included. This tool uses the 52-card rules with King-Ace connection. When both players are stuck, one card each is drawn from the stock piles to the field to continue play.
