About MaffDoku

Maffdoku is a math-based puzzle game. Think of it as a Sudoku with an extra dose of mathematial fun! The objective is to solve the 3x3 grid by placing the numbers 1-9 in their correct position. To do that, you need to use the clues in the outer ring. Each number in the outer ring is a total for that row or column. Numbers at the top or left are "Ξ£" totals and represent the sum of that line (a+b+c). Numbers at the right or bottom are "Ξ " totals and represent the product of that line (a*b*c). Using these clues and a process of elimination, you should be able to solve the puzzle.

Playing MaffDoku

Select one of the squares in the 3x3 grid then use the keyboard to enter a number. Choose pen mode (click 'πŸ–ŠοΈ') to write in your answer. Choose pencil mode (click '✏️') to enter your workings and make a note of any possible answers that remain. Click 'πŸ”„' to undo any moves.

Hints

If you get stuck, click 'πŸ‘€' to reveal a hint. Firstly, a hint will reveal any incorrect answers. If nothing is incorrect, it will reveal a new square - either a new total or one of the 3x3 answer squares.

Levels

There are three Maffdoky levels. We suggest you start at level 1 and see if you can progress to levels 2 then 3.

Tactics

There is only one possible answer to each puzzle. Finding that answer requires tactics that might be familiar to Sudoku players. Try to complete a row or column based on the clues given. You might also need to eliminate various possibilities based on what numbers must go elsewhere. You can even try trial and error.
