MathDoku is an excellent game that combines arithmetic and math skills with logical reasoning. Numbers can only appear once in each row and column. The 4x4 board contains the numbers 1 to 4, the 6x6 the numbers 1 to 6, and the 9x9 the numbers to 9. This rule is identical to the rule that also applies to the popular game Sudoku. Grids are divided into so-called cages composed of groups of white cells (2, 3, 4 or more depending on the size of the grid), target numbers and operators (addition, subtraction, multiplication and division). Target numbers are sums, differences, product or quotient of mathematical operations. Use your math and logic skills (if you have them, of course) and become an arithmetic MathDoku wizzard. Just like Sudoku, Hidato and Numbrix, MathDoku can only have one possible solution.
