Online logic games

Logic games you win by reasoning rather than by luck. You can play them in your browser, free, with no account and nothing to download.

Solve it by deduction

Crowns and Sudoku Six are about ruling out what cannot be true until only one answer is left. Trail asks you to plan a route before you box yourself in. Target Number turns the same kind of thinking onto arithmetic.

Choose how hard it gets

Each game has three levels. The grids get bigger or give you less to start from, so you can warm up on Easy and move up when it stops being a challenge.

Alone or against someone

Play on your own to improve your time, or share a room code and give your friends the same puzzle at the same moment. Fast wins go into the records of the Hall of fame.
