About

Null Pattern

Features
Read full description

Null Pattern is a minimalist logic puzzle game about transforming grids, reading patterns, and finding the exact sequence of moves that clears the board. Each level gives you an initial grid and a target pattern. Tap cells to trigger changes, study the result, and work your way toward the solution. Early puzzles teach the rules gently, but the challenge ramps up fast. Later levels demand careful thinking, efficient moves, and a willingness to stare at the grid until the hidden logic finally clicks. Features: - Elegant grid-based logic puzzles - Increasingly difficult levels that reward planning - Clean visual design focused on the puzzle - Par move goals for players who want an extra challenge - Great for quick sessions or deep puzzle-solving runs Null Pattern is easy to start, but it is not afraid to get tough. If you enjoy compact puzzle games with real bite, this one is built for you.
