About
"0h n0" is a grid-based puzzle game where players fill in blue and red dots according to three rules: blue dots can see others in their row and column, their numbers indicate how many are visible, and red dots block their view. With unlimited puzzles and no pressure, players can choose their grid size from four options and can play in zen mode or beat their personal best time in time trials. The game is free, without ads, social network requirements, or locked features, making it a gift to players.
