THW's Calcudoku is the most fun and addictive logic puzzle since Sudoku. Based on the same logic grid as Sudoku, where each row and column contain the numbers 1-9 exactly once, Calcudoku layers on top + - x ÷ operations in a brain-bending twist. Use logic and math to figure out which number goes where.

Hey, I'm well aware that logic is a kind of math, don't at me

So why THW's? I made this game because no Calcudoku-style app worked the way I wanted it to. Then I thought "Well it should work the way you want it to, too". This means you can CUSTOMIZE ALMOST EVERYTHING! No really, even tiny little details.

Lovingly crafted by an avid player, THW's Calcudoku has many features to help players of any skill level crack these puzzles open.

FUN PUZZLES! THW's has an original engine for building puzzles that takes size, difficulty, and FUN into consideration.
