Mau Mau is a puzzle card game, its rules are the same as Crazy Eight. Just change 8 to J. The rule is that the cards you play should be the same color or number as the bottom cards. Otherwise, a card will be taken out of the reserve card. If the cards are of the same color or number, they will play directly, and vice versa. The game goes out until a player has all the cards in his hand. Settlement results. Four games are one round. Be careful with props.
