Mathdoku Guru (Math Logic Puzzle to Train Your Brain) app for iPhone and iPad

Mathdoku/Calcudoku is the next Sudoku! A simple math logic game that is easy to learn but challenging to master.

Here are the rules...
Fill the Grid with digits. The digits within each heavily outlined box (called a cage) will produce the target number shown in that cage by using the operation (addition, subtraction, multiplication, or division) shown by the symbol after the numeral.

For example, target number is 6+ means that the numerals in the cage should add up to 6, and target number 48X means that by multiplying the numbers in the cage you will get 48.

For single box cages, simply enter the same digit as the target number.

Do not repeat the same digit in any row or column.

A 4X4 grid will use the digits 1-4, A 5X5 grid will use 1-5. A 6X6 grid will use 1-6, and so on.

Test your mental skills with 100 levels (from Easy 3 x 3 to Pro 9 x 9 Grids). Train your Brain and be a Guru of math logic!
