Dotty Dozen

This is a children's card game. Each player has three cards in hand, cards can be numbered 0 to 6. On their turn, they play one of them to one of the 4 stacks. If the 4 top cards now add up to 12, they take those 4 top cards and immediately take another turn. Note: Cards must first be played to open spaces in the tray. A sum of 12 must always be made with 4 cards. Hands must always be refilled to 3 cards. Game ends when last card is played. Winner is the player with the most cards.
