Hint

What's Sudoku?

Sudoku is a logic-based puzzle originating from Japan. It gained widespread popularity after appearing in The Times (London) in 2004 and is still loved to this day!

How to Play

The goal of Sudoku is to fill the grid so that each row, column, and 3x3 square contains every number from 1 to 9 exactly once.

Quick Tips

  • There's no guessing involved; each number can be deduced with logic.
  • Look at the areas that contain the most numbers.
  • Use notes to mark squares that only have two possibilities.
