Card Games


Concentration is a card game where all cards are placed face down, and players attempt to uncover pairs. Each player takes turns flipping over two cards and removing them if they match. The goal is to collect as many pairs as possible until all cards have been matched and removed. Press the Play button to start the game (Fig. 1).
