How to Play LinkedIn Mini Sudoku

Mini Sudoku is LinkedIn’s quick 6×6 sudoku: fill the grid so every row, column and 2×3 box contains the digits 1 to 6.

Rules

  • Fill every empty cell with a digit from 1 to 6.
  • Each row contains every digit once.
  • Each column contains every digit once.
  • Each 2×3 box contains every digit once.

How the game works

Some digits are given at the start. Select an empty cell and enter a digit; the puzzle is solved when every row, column and box contains 1 to 6 exactly once.

Beginner strategy

  • Start with the row, column or box that already has the most digits.
  • Look for a cell where only one digit is still possible.
  • Look for a digit that has only one possible cell in a row, column or box.
  • Scan each digit 1 to 6 across the grid to see where it can still go.

Common mistakes

  • Treating the boxes as 3×3 out of habit.
  • Repeating a digit within a box.
  • Guessing instead of checking the row, column and box together.

Example

The shaded digits were given at the start. In the finished grid every row, column and 2×3 box contains 1 to 6 exactly once.
