Two big and one small cards in a row in the team picture. A and K can be continuous, Q can team with J, K. 3 can team up with 2, 4. Joker can team up with any card. When the time is over, if there are cards other than Joker in your card pool, the game is judged as a failure. When the time is not over, there is no Joker on the interface and there are no connectable cards. !!
