Stack SEVEN is out: a free card game of stacking 7s and a Hidden Joker

Stack SEVEN - The Hidden Joker is out, and you can play it free in your browser right now, on phone or desktop.

▶ Play at https://stackseven.io

What it is

A fast, low-score card game for 2 to 8 players. Discard first, then pick. Play a 7 and the next player draws 2, unless they stack a 7 of their own and pass a bigger penalty on. Every round a Hidden Joker is set aside; after everyone's first turn it flips, and every card of its rank is worth 0. Under 10 points, you can call SHOW: be strictly the lowest and you score 0, get it wrong and you take 80. Seven rounds, and the lowest total wins.

What's in the launch

• An instant table against three bots, or a private room with a code for your friends
• Tables from 2 to 8 players, with bots that fill empty seats and finish for anyone who leaves
• A 2-minute tutorial
• A seasonal leaderboard and room chat
• The Founders' season: finish a match before 31 December 2026 and keep the Founder card back for good
