## What is Binairo?

Binairo is a pure logic puzzle. A grid, two colours, and nothing to do but deduce.

Three rules, that's all:

never three cells of the same colour side by side, in a row or a column;
as many cells of each colour on every row and every column;
no two rows are ever identical, and no two columns either.
No grid is ever guessed. Every board is fully deducible, from the first cell to the last. If you are stuck, there is still something to see — never a coin to flip.

A new grid every day, the same one for every player in the world. Gentle on Monday, tougher at the weekend. Play day after day to build your streak, and share your result without spoiling the solution.

Unlimited practice in three sizes when one grid a day is not enough.

No account, no sign-up, no connection needed to play. Light and dark mode. English, French, Spanish and Portuguese.

A game by Korun studio.
