Euclid.The.Game

Find hidden squares, outsmart your opponent, and tackle daily and weekly puzzles. Play solo, share a device, or challenge friends online.

See the square. Set the trap. Steal the win.

Four corners make a square. Spot one your opponent missed, block their next move, or complete several at once to turn the game around.

Euclid is a strategy game about seeing what’s hiding in plain sight. Squares can be straight or tilted, tiny or enormous. Bigger squares score more. The best move isn’t always the obvious one.

• Challenge Euclid across nine difficulty levels. • Play together on one device, invite a friend online, or compete in ranked matches. • Solve shared daily and weekly puzzles in as few moves as possible. • Try Tide, where pieces disappear and timing changes everything. • Take an offline game along with the Apple Watch companion.

Free on iPhone and iPad. Ads appear only on Home, with a one-time purchase to remove them. Offline practice and local two-player games need no internet.

Four corners. One brilliant move. Can you see it?
