Stress is a speed-based, simultaneous play, standard deck playing card game. The object is to get matched sets of cards face value.. You begin by dealing four cards to the center, and equal stacks of four cards to each player. Therefore, for three players there will be four face-up cards in the center, and each will have three stacks of 4 cards in front of them. Players swap single cards with the center until a stack has 4 of the same face value. They then flip the set over. Once all of their sets are flipped over the player says "Stress" to indicate they've won.
