0h h1 is an addictive game for young and old. It is a small logic game where you have to fill the grid with red or blue tiles. 0h h1 follows three simple rules: 1. No three red tiles or three red tiles next to each other in a row or column. 2. A complete row or column should have as many blue tiles as there are red ones. 3. No two lines are the same. There are neither columns.
Easy to learn but difficult to master.
