Sudoku

This logic-based number-placement puzzle swept the world in the early 2000s and is a cornerstone of any puzzle section. Place the numbers 1 to 9 in each row, column and 3x3 square without repetition to complete the grid.

We can provide puzzles to challenge any solver, from beginners to experts. Our interface includes an inbuilt numberpad with a button to enable 'Pencil Mode'. When activated, this allows the player to input multiple 'possible' solutions for the selected square, before eliminating their way to the correct one.

The menu in the top right allows you to check your answers, get a number as a hint, reveal the entire solution, print the puzzle, turn sounds on or off, view the puzzle leaderboard and save or clear your progress.
