About

0h h1 is a minimalist logic puzzle where you fill a grid with red and blue tiles while avoiding specific patterns. Each move must prevent three identical colors in a row or column, ensure every line has equal red and blue tiles, and keep all rows and columns distinct. The challenge grows as grids expand, requiring careful planning and quick adjustments. Playable in short bursts, it’s all about balancing constraints with clarity. The game’s stark design and strict rules create surprisingly deep problem-solving. Despite its simplicity, it’s been played over a million times on its original site. The web and mobile versions let you tackle puzzles anytime, with no ads or distractions. It’s a quiet test of logic that rewards patience more than speed.
