OH REALLY? Yes. For one low price you can have infinity ad-free puzzles of any difficulty. You can even make your own and share them with friends. No waiting 30 seconds for an ad to play, no additional costs for more puzzles, no subscriptions, I hate all that stuff. Just fun puzzles for one price once.
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.
Enjoy logic but have trouble with the math? There are several different types of help available.

FUN PUZZLES! THW's has an original engine for building puzzles that takes size, difficulty, and FUN into consideration. These are not randomly generated abominations or AI-created nightmares, these are built from the ground up to be the right level of difficult, enjoyable, and most importantly solvable.
INFINITE HISTORY! With the new puzzle history feature you can stop a puzzle any time, play different puzzles, and come back to the old one whenever you're ready. Stuck on one board but still want to play? Just start a new one, the one you were playing is automatically saved. Easily filter your history to find the right puzzle. Keep your history forever or set a cap to save space.
NICE LOOKING THEMES I GUESS MAYBE! Use any of the totally radical built-in themes or make your own. If all you want is black and white like the newspaper, have at it. If you want a trippy lava lamp kinda thing you can have that too. Throw your dog up in there, why not
