How to Play a 4x4 Sudoku Puzzle

A 4x4 sudoku puzzle is a simplified version of the classic 9x9 game, using a 4×4 grid divided into four 2×2 boxes. The goal is to fill the grid with the numbers 1 to 4 so that each number appears exactly once in every row, every column, and each box. The numbers given at the start of the puzzle must remain unchanged. You only fill in the empty spaces using logic, not guessing.

Sudoku puzzles help improve concentration, memory, and logical thinking. The 4x4 format is especially great for young learners or those new to sudoku, providing a gentle way to train the mind.

How does difficulty work in 4x4 sudoku?

The difficulty is determined by how many numbers are provided at the start, and how they’re arranged. Fewer starting numbers mean a greater challenge, while more clues make solving easier. Even in a 4x4 grid, logic still rules.

Tips for solving a 4x4 sudoku puzzle

Start with rows or columns that already have more numbers filled in. Think about where each number could go without breaking the rules. Use a pencil and take your time. No guessing, just logic.
