How to play: You play against a CPU opponent with a standard double-six domino set (28 tiles). Each round both players draw 7 tiles; remaining tiles form the stock. Click a highlighted tile in your hand to play it on a matching end of the chain (if both ends match, choose left or right). If you have no valid move, draw from the stock until you can play or the stock is empty (then you must Pass). The round ends when a player empties their hand (scoring the opponent's remaining pip total) or the game is blocked (lowest pip total wins the difference). First to empty hand or best score after blocking wins each round — scores accumulate across rounds.
