How to Play Mini Sudoku

Simple rules

  • Objective: Fill the 4x4 grid with numbers 1-4 so that each row, column, and 2x2 box contains all four digits exactly once.
  • Gameplay: Click an empty cell to select it, then click a number from the palette to place it.
  • Controls: Use Undo to revert your last move or Erase to clear a selected cell.
  • Winning: When all cells are correctly filled, you've solved the puzzle! Use Check to validate your solution.

Strategy & Tips

Improve your solving speed

  • Start with Obvious Numbers: Look for rows, columns, or 2x2 boxes that already have numbers filled in. These are easier to complete.
  • Use Process of Elimination: If a row already has 1, 2, and 3, the remaining cell must be 4.
  • Check All Constraints: Remember each number must appear once in each row, column, AND 2x2 box.
