HOW TO PLAY
Click on the grid to fill it with numbers. Each row and column must have exactly one of all the possible digits used, just like sudoku. For example, in a 4x4 puzzle, each row and column must have exactly one of the numbers 1, 2, 3, 4.
Squares outlined in thick lines are little math puzzles. The solutions and operations are printed in it. For example, if the solution is 3-, possible solutions are 4, 1 and 1, 4. Order does not matter.
