0h h1 is a little logic game that follows three simple rules:

- Three red tiles or three blue tiles next to each other in a row or column isn't allowed

- A full row or column must have as many blue tiles as it has red ones.

- No two rows are the same. No two columns either.

Simply tap a tile to make it red or blue and complete the grid.

0h h1 gives you unlimited puzzles for all four grid sizes:

4 x 4

6 x 6

8 x 8

10 x 10

0h h1 is free, without ads, without social network requirements, without locked features and without nag screens. 0h h1 is a little gift to you. We hope you enjoy it.
