0h h1 is a little logic game by Q42.
It follows three simple rules:
1. Three red tiles or three blue tiles next to each other in a row or column isn't allowed
2. A full row or column must have as many blue tiles as it has red ones.
3. 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.
