Three pairs. One risky knock.

A small hand with a lot to think about

You have six cards in three rows of two. Matching positive ranks cancel out. Aces and Jokers take points away. Most cards begin face down, so nobody knows quite how good their hand is.

On your turn, swap in a useful card, draw from the deck, or flip one of your hidden cards. Think you have the lowest score? Knock at the end of your turn. Everyone else gets one last turn. If you guessed wrong, their points are added to yours.

Get a table together

1. Choose a name and one of the card-room characters.
2. Create a private room and share its four-letter code or invitation link.
3. Add friends or computer players, then deal. The game handles the cards and scorecard.

Private rooms do not need accounts. Each person uses their own browser. Play with 2 to 8 seats, or choose solo to fill the other chairs with computer players. The host can choose 3, 6 or 9 rounds and add an unscored practice round.

Learn a little, then play

Read the complete Sixes rules for the turn sequence and the last-turn rules. The interactive pair scorer shows exactly how every pair works, and the strategy guide explains how to judge a knock without pretending to know hidden cards.
