With the loss of Microsoft Sudoku from this website, we are looking for substitutions for you to enjoy for your daily logic brain-training. This modest Flash game is called “Just Sudoku”. It features 25 puzzles to figure out, divided across 5 difficulty levels. 

Click an empty space and select a number to enter.

A number may not appear more than once in a row, or “square” (delineated by the thicker border).

Fill in all spaces correctly to solve the puzzle!
