How to Play MathDoku

All the same rules as standard sudoku apply, but segments are now unique to each puzzle instead of always being nonets. This spin on the game tests your arithmetic skills by adding target numbers with operators in the top left corner of each segment. The numbers in the segment must produce the exact target based on the operator provided. Don't worry though, we've provided a calculator that you can use as much as you like without any penalty to your score.
