The gameboard consists of 5x5 squares numbered 1-25. Each player is dealt 5 cards. Players alternate turns in which they play their colored cards onto the gameboard on eligible squares. Any square that is not locked is eligible to be played on, even if the opponent has previously played on the square. After each turn, the player draws another card. If they can not play a card, they discard one and draw another. The game continues this way until the game ends. The player with the most points at the end of the game wins. Source: The Game Website.
