Sudoku is an excellent way for kids to develop their logic skills while having fun, and children as young as 7 or 8 can begin to enjoy them. No maths is needed to complete the puzzles, and no guessing should be necessary either! Sudoku is not exactly a mathematics game, but most of us are using them in our classrooms anyway! Sudoku is a logic game and logic skills are very welcome to math teachers and students! There are quite some variations in the Sudoku layouts, but we feel that the simple 9 by 9 game is the most effective! The rules are actually very easy. Let's keep the 9 by 9 Sudoku in mind. The numbers 1 to 9 (it's a 9 by 9 game) must be filled in each row, column and box. This box will be a 3 by 3 box in the 9 by 9 variation of Sudoku! Each number can and must be filled in only once! The normal 9 by 9 version looks like follows: Each puzzle will already have numbers filled in depending on the difficulty level. The more numbers already filled in, the easier most likely.
