0h h1 is a little logic game that will put your puzzle-solving skills to the test. With its simple yet addictive gameplay, this game is perfect for those looking for a brain-teasing challenge.

The game follows three simple rules: first, you must avoid having three red tiles or three blue tiles next to each other in a row or column. Second, each row or column must have an equal number of blue and red tiles. And finally, no two rows or columns can be the same.

To play, simply tap on a tile to make it red or blue and complete the grid. The game offers unlimited puzzles across four different grid sizes: 4x4, 6x6, 8x8, and 10x10.

What sets 0h h1 apart from other puzzle games is its simplicity and accessibility. It is completely free, without any ads, social network requirements, locked features, or nag screens. It's a little gift from the developer, Q42, to puzzle enthusiasts everywhere.
