Crazy Eights has spawned more variants than almost any other card game. From the German Mau-Mau to the British Switch to countless custom rule sets, the core suit-and-rank matching mechanic has been customized by generations of players around the world. This guide covers every major variant and the special card rules that define them.

The Base Game

Before diving into variants, here’s the standard Crazy Eights framework they all modify:

  • Match the discard pile by suit or rank
  • Eights are wild — play any time, declare next suit
  • Draw when you can’t play
  • First to empty their hand wins

Every variant below keeps this foundation and adds or changes specific elements. If you need a full refresher, see the complete rules guide.

Mau-Mau (Germany)

Mau-Mau is one of the most popular card games in Germany, Austria, and Switzerland. It’s played with a 32-card deck (7 through Ace in each suit) rather than the full 52.

Special Card Powers in Mau-Mau

Card Effect
Jack Wild card (replaces eights) — play on anything, declare a suit
7 Next player must draw 2 cards (stackable)
8 Next player’s turn is skipped
Ace Reverse direction of play (in 3+ player games)

Key Mau-Mau Rules

  • Announcement rule: When you have one card remaining, you must say “Mau.” When you play your final card to go out, you must say “Mau-Mau.” Failure to announce results in drawing 2 penalty cards.
  • Stacking 7s: If someone plays a 7, the next player can play another 7 instead of drawing. The penalty accumulates — two 7s means the next player draws 4, three 7s means 6, and so on.
  • No ending on a Jack: In some versions, you cannot go out by playing a Jack (wild card). You must play a non-wild card to win.
  • 32-card deck: Using only 7–Ace speeds up the game and makes every card more impactful.

Mau-Mau Strategy Notes

The smaller deck makes card tracking more feasible. With only 32 cards in play, you can more reliably estimate what opponents hold. The stacking mechanic on 7s creates dramatic moments where penalties spiral — always keep a 7 in hand if possible as insurance.

Switch (United Kingdom)

Switch is the dominant Crazy Eights variant in the UK and parts of the Commonwealth. It’s played with a full 52-card deck and adds multiple action cards.

Special Card Powers in Switch

Card Effect
2 Next player draws 2 cards (stackable)
Ace Wild card — play on anything, declare a suit
Jack Skip next player’s turn
Queen Reverse direction
Black Jack Next player draws 5 cards (in some versions)

Key Switch Rules

  • Stacking draw cards: If a 2 is played, the next player can play another 2 to pass the penalty along (+4 total). This continues until someone can’t stack — they draw the accumulated total.
  • Last card announcement: You must say “Last card” when playing your second-to-last card. Forgetting means drawing a penalty card.
  • Aces are wild (not eights): This is the biggest departure from standard Crazy Eights. Aces serve the wild card function.
  • Playing on action cards: You can play a matching action card on another action card to deflect or stack the effect.

Why Switch Is Closest to UNO

Switch essentially is UNO played with a standard deck. Draw twos, skip cards, reverse cards, and wilds — these are the same four action mechanics UNO uses. The main difference is that Switch doesn’t have a Wild Draw Four equivalent, and the action cards are identified by rank rather than being printed on the card.

Last Card (New Zealand / Australia)

Last Card is the standard shedding game in New Zealand and parts of Australia. It closely resembles Switch but with some distinct rules.

Key Last Card Rules

  • Mandatory announcement: You must say “Last card” when you’re down to one card. Failure is penalized with a draw.
  • Pickup (draw) cards: 2s force a draw of 2, and in some versions Aces force a draw of 5.
  • Jacks are wild: Like Mau-Mau, Jacks serve the wild function in most Last Card versions.
  • Knocking: Some versions allow knocking on the table instead of verbal announcement.

Regional Differences

Last Card rules vary noticeably between families and regions, which is part of its charm — and part of why UNO’s printed rules appealed to standardization-minded players.

Pesten (Netherlands)

Pesten (Dutch for “bullying” or “teasing”) is the Netherlands’ version of the Crazy Eights family. True to its name, it emphasizes aggressive card play.

Pesten Special Cards

Card Effect
2 Next player draws 2 (stackable)
7 Next player draws 2 or plays a 7
8 Skip next player
Jack Wild, declare suit
Ace Reverse direction
Joker Next player draws 5 (in versions using jokers)

Pesten is notable for using Jokers as the most powerful penalty card. Some versions include both jokers in the 54-card deck, making them the nuclear option — 5 cards drawn at once, and they’re stackable.

Other Regional Variants

Prší (Czech Republic / Slovakia)

  • Played with a 32-card German or French deck
  • 7s force draws (2 cards)
  • Aces skip next player
  • The name means “It’s Raining” — possibly referencing the rain of penalty cards

Uno (Commercial, Global)

Technically the most-played Crazy Eights variant, UNO formalized house rules into a printed deck. For a full comparison, see Crazy Eights vs UNO.

Macau (Eastern Europe)

  • 2s and 3s are both draw cards (draw 2 and draw 3 respectively)
  • 4s skip, Aces are wild
  • Heavy stacking culture — games can have draws accumulate to 10+ cards

Tschau Sepp (Switzerland)

  • Swiss variant using Jass cards (36-card Swiss-German deck)
  • 6s skip, 7s force draws, Jacks are wild
  • Must announce “Tschau” with one card, “Tschau Sepp” when going out

Special Card Rule Variants

Independent of regional versions, specific card powers can be added to any Crazy Eights game. These are the most common:

Draw Two

Which card: 2s (most common) or a specific rank agreed upon before the game.

Rule: When a 2 is played, the next player must draw 2 cards and forfeit their turn — unless they can play a 2 of their own, which passes the penalty (now 4 cards) to the next player.

Impact: Adds a confrontational element and makes 2s valuable defensive cards.

Skip Turn

Which card: Jacks (most common) or Queens.

Rule: When a skip card is played, the next player loses their turn. Play passes to the player after them.

Impact: Powerful in two-player games — playing a skip card means you play again immediately.

Reverse Direction

Which card: Queens (most common), Aces, or Kings.

Rule: When a reverse card is played, the direction of play changes from clockwise to counterclockwise (or vice versa).

Impact: In two-player games, a reverse acts as a skip (you play again). In multiplayer games, it changes the whole table’s dynamic.

Draw Five

Which card: Jokers (when included in the deck) or Kings.

Rule: The next player must draw 5 cards. Usually not stackable due to the severity.

Impact: A game-changing penalty. Often used with Jokers added to the deck.

Play All Matching

Rule: If you hold multiple cards of the same rank, you may play them all at once.

Impact: Speeds up the game and rewards players who collect matching ranks.

Building Your Own Variant

The beauty of Crazy Eights is that the base mechanic is so solid that almost any combination of special card rules works. Start with the standard rules, add the special cards you enjoy, and write them down. You’ve just done exactly what Merle Robbins did before inventing UNO — and what millions of families have done for nearly a century.
