This full-pack household profile permits jack on jack and immediate use of a legal drawn card. Other families forbid these; agree the profile before play.

Four hands of 5, a 9♦ starter and 31 stock complete the 52-card pack. This ordinary starter activates no special-card penalty.

A familiar name with local house rules

Mau Mau belongs to the matching-and-shedding family played widely in Germany and neighbouring countries. It shares a mechanism with Crazy Eights, but named cards and calls vary by household. Short Skat packs are traditional in some German regions; this guide uses the full international pack. There is no claim that every family uses this exact code. We select stackable sevens, skipping eights and wild jacks, with no ace or king powers and no reverse card. A precise inventor is not established.

Deal five and activate the starter

For 2–6 players use 52 cards without jokers. Choose dealer randomly and rotate clockwise. Deal 5 each singly, place remainder face down, turn 1 starter. With 4: 20 held, 1 discard and 31 stock. Start left of dealer, clockwise. A starter 7 begins a draw-2 obligation, an 8 skips first player, a J lets dealer name the starting suit. All other starters simply show suit and rank. Agree the scored-match target of 100 penalty points before beginning; the least total will win.

03 /

One match or one draw

Normally play 1 card matching the top discard’s rank or suit. If no legal play, draw 1; you may immediately play that drawn card if legal, otherwise keep it and end the turn. Do not play a different hand card after drawing. A J may be played on any normal top, including another J, and names any suit. After a J, play that named suit or another J; the jack’s printed suit is irrelevant. There is no obligation to beat a card, no trump and no trick capture.

04 /

Sevens accumulate, eights skip

A played 7 imposes 2 cards on the next player. They may play any 7 instead, adding 2 to the pending debt; otherwise draw the whole debt and lose the turn. A J or an 8 cannot cancel it, and penalty cards cannot be played immediately. Once paid, debt clears and the last seven supplies the ordinary suit and rank. An 8 skips the next seat; with 2 players you play again. Refill an empty stock by shuffling old discards while preserving the top and any named suit or pending debt.

Mau, Mau Mau and a fair finish

Say “Mau” after a play leaving 1 card and “Mau Mau” with the last. If another player notices a missing call before the next player completes a turn, draw 2 and continue instead of winning. A correctly called last card wins immediately, even a special card: this profile does not collect a final seven penalty after the finish. For disputes pause before moving more cards. If a required draw is impossible even after recycling, our explicit fallback stops the round and scores hands as held; no empty-hand winner is awarded.

Penalty totals, not card strength

Winner records 0. Others count every held card: A K Q J cost 10 each, numerals face value. Add round totals; after any player reaches 100, lowest cumulative total wins, ties share in this selected profile. The card that caused a penalty has no extra score multiplier. For example K♣ 7♦ 2♠ costs 10 + 7 + 2 = 19. A missed call adds cards to the hand rather than a fixed score deduction. A short casual game may stop after one round, agreed before dealing.

A chain adds two, never doubles

A plays 7♥. B responds 7♣, passing debt of 4. C plays 7♠, passing 6, not 8. D has no seven and draws 6 without playing, then A acts on 7♠ normally. These are individual turns; D cannot dodge the debt with J♦. In a separate position with no debt, A plays J♦ naming clubs; B must play a club or another jack, not any diamond. The diagrams show local examples rather than a full deal.

The debt grows by two. A → B → C: 7♥, 7♣, 7♠. A plays 7♥, B 7♣, C 7♠. Each passes to the next seat: 2 → 4 → 6, not 8. Pay without playing. D’s penalty draw: Face down, Face down, Face down, Face down, Face down, Face down. On table: 7♠. D has no seven, draws six and loses the turn. A now matches 7♠ normally; D cannot use a jack to cancel debt. Separate jack example. Jack · clubs named: J♦. Legal response: 4♣. No debt: J♦ names clubs. Next player may play 4♣; the jack’s printed diamond does not force diamonds. 7♥, then 7♣, then 7♠ create a debt of six cards, not eight. A wild jack changes the required suit only when no seven debt is pending.
