About this game
Stack SEVEN - The Hidden Joker is a fast, low-score card game for 2 to 8 players. Play it in your browser against bots or with friends. No download, no sign-up.
How it plays
- On your turn, discard first (one card, or several of the same rank), then pick a card from the draw pile or from what the previous player just discarded.
- Play a 7 and the next player must draw 2. Unless they stack another 7 on it and pass a bigger penalty along.
- Every round one card is secretly set aside: the Hidden Joker. After everyone's first turn it flips, and every card of its rank is worth 0 for the rest of the round.
- Under 10 points? Call SHOW to end the round. Be strictly the lowest and you score 0. Get it wrong and you take 80.
- Seven rounds, with rounds 1 and 7 counting double. The lowest total wins.
