🎯 How to play Mini Sudoku
Mini Sudoku is a smaller version of classic Sudoku. Fill the 4×4 grid using the numbers 1, 2, 3 and 4. Each number must appear exactly once in every row, every column and each outlined 2×2 box. You do not need to add or calculate numbers: solve by eliminating impossible placements.
💡 Mini Sudoku solving tips
Find the missing numbers in a row, column or 2×2 box that already has several clues.
Check the crossing column and box before placing a number.
Mark possible candidates when a cell has more than one option.
Look for a number that can fit in only one remaining cell.
