Мау-мау

Use a 32-card deck (7s through Aces) for authentic rules, or a standard 52-card deck. Deal 5-6 cards each. Place the deck as a draw pile and flip one card to start the discard pile.

The first player to correctly discard all cards and say 'Mau Mau' wins. Remaining players count their cards against them for scoring.

Play a card matching the discard's suit or rank. If you cannot play, draw one card and either play it or pass. Special cards: 7 makes the next player draw two cards (stackable). 8 skips the next player. Jack is wild - play anytime and call a new suit.

Save your Jacks for when you need to change suit. Stack 7s if possible to force massive draws onto the next player. Remember to say 'Mau' - forgetting costs you penalty cards.

Mau Mau originated in Germany and became popular across Europe. The game likely developed in the early 20th century. It's known by many regional names with slightly varying rules.
