Two teams. You and two teammates play against three others. You see only your own cards, and no one may say what they hold.
Sets of six. The cards come in nine sets of six. Your team wins by claiming more sets than the other team.
Your turn. On your turn, do one of two things: ask for a card, or claim a set.
Ask within a set. You can ask for a card only if you hold at least one card from its set.
Ask for a card. Ask someone on the other team for a card. If they have it, it is yours and you ask again. If not, it is their turn.
Claim a set. When your team holds all six cards of a set, claim it and say who has each one. Get one wrong and the other team gets the set.
Who plays next. After a claim the six cards leave the game. Whichever team gets the set picks who plays next.
Win five sets. Play until all nine sets are claimed. The team with five or more wins.
All the rules
Players
Six players in two teams of three, or eight in two teams of four. Teammates sit apart.
Cards
54 cards in nine sets of six: the 2 to 7 and the 9 to Ace of each suit, and the four 8s with the two jokers. All the cards are dealt; with six players, everyone gets nine.
Your turn
Do one of two things: ask for a card, or claim a set.
Asking
Ask a player on the other team who still has cards. You must hold a card from the same set, and you cannot ask for a card you hold. If they have it, they give it to you and you ask again. If not, the turn passes to them.
Claiming
On your turn, when your team holds all six cards of a set, say which teammate holds each one. All six right: your team gets the set. One wrong: the other team gets it. Either way, the six cards leave the game.
After a claim
The team that got the set chooses which of its players goes next.
Out of cards
A player with no cards cannot ask, claim or be asked. If the turn comes to them, they pass it to a teammate who has cards.
No hints
Do not tell anyone which cards you hold, not even your teammates.
Winning
The game ends when all nine sets are claimed. The team with five or more sets wins, so there is always a winner.
