Challenge yourself with numbers

If you are not familiar with Sudoku, let us just say that it is a puzzle game that absolutely hates repetition. Players are given a 9×9 grid with 3×3 subgrids and the numbers 1-9 occupying some of the spaces. The goal is to fill up all the blank squares, also with numbers 1-9 but the catch is that they should never repeat within the same grid, row, and column. Sudoku features different difficulty levels that could match your own skill level. The game is also timed so you can see how long it usually takes you to finish a sudoku puzzle.
