Sudoku Light

About This Game

Sudoku Light strips the classic number puzzle down to a fast, approachable 4x4 grid. Instead of the intimidating 9x9 grid with 81 cells, you get 16 cells organized into four 2x2 blocks. The rules are the same — each row, column, and 2x2 block must contain numbers 1 through 4 exactly once — but the smaller grid means games take 1-3 minutes instead of 20.

We built this because we wanted a Sudoku game that didn't feel like homework. The timer adds mild pressure, three hints are available per game if you get stuck, and the puzzle generator guarantees every layout has a unique solution. It's the perfect coffee-break brain workout.

Controls

On mobile, tap a cell then tap a number button. The hint button reveals one correct cell — use it sparingly, you only get three.
