Threezy is a free, browser-based card puzzle in the spirit of the classic card game SET. Spot a “set” of three cards as fast as you can, beat the clock, and climb the global leaderboards — no download, no signup, on any device.
Every card has three features: shape, color, and fill. Three cards form a valid set when, for each of those three features, the three cards are either all the same or all different. Tap the three cards that make a set; find as many as you can. There is always at least one set on the board.
It’s free and instant — open the page and play. A fresh daily challenge, an endless Flow mode, global and country leaderboards, fastest-chain and marathon rankings, an ELO skill rating, and 80+ achievements to chase. Great brain training for fans of pattern, logic, and speed card puzzles.
