A round of play.
- The starter plays a combination.
- In turn, each plays a higher combination with the same number of cards – or passes.
- Among five-card hands, a higher type beats any lower type (a flush beats any straight).
- When everyone else has passed, the player who played last starts a new round.
Example with Players 1 to 4. Order: Player 4, 1, 2, 3.
- Player 4 plays the 3 of diamonds + 3 of spades (pair).
- Player 1 plays a pair of nines. Player 2 plays a pair of jacks. Player 3 passes.
- Player 4 passes. Player 1 plays a pair of twos (2 of hearts, 2 of clubs) – hard to beat.
- Player 2 holds the 2 of spades and 2 of diamonds. With equal rank the highest suit in the pair decides: Player 2's 2 of spades is the highest card of all. His pair beats Player 1's, and he plays it.
6. Scoring
- Penalty points: Each loser scores 1 point per card left.
- Many cards: With 10 or more cards left they count double, with 13 cards triple (variant).
- Twos in hand: In some games each two left in hand doubles the penalty.
- Recording: One column per player; fewest points win.
7. Special rules and situations
- 3 of diamonds first: The first player must use the 3 of diamonds in their first combination.
- Comparing pairs and triples: Higher rank wins; with equal rank, the highest suit.
- Straights: A-2-3-4-5 and 2-3-4-5-6 are allowed differently by region – agree beforehand.
- Last card warning: A player with one card left announces it; the player before them must then play their highest single if playing a single.
- Common mistakes: using twos too early; answering with the wrong number of cards.
