Developer Description
Enjoy Calcudoku, a number puzzle game that tests your logic! Plays like Sudoku!
About Calcudoku number puzzles:
Every Calcudoku has a single solution that can be reached logically. Like Sudoku, Killer Sudoku and KenKen®, fill in the grid such that no two digits repeat in any column or row. Use the shapes in the grid as your guide. Each shape contains a number equaling the product of the shapes' digits. For example a shape with three cells containing the number 6 may have cell values 1, 2 and 3, as 1 × 2 × 3 = 6. Challenge yourself further with larger grids for experts, up to 9x9 size!
Calcudoku offers thousands of fun number puzzles with features to help you solve each puzzle. Enjoy an unlimited number of hints and checks in case you get stuck. Use the calculator tool to help with multiplication and division against large numbers. And rest assured that all puzzle games are automatically saved and restored letting you stop and restart games with ease.
Track your best and average solve times over history with our stats tracker.
Calcudoku, a popular Killer Sudoku variant, was originally invented in 2004 by Japanese math teacher Tetsuya Miyamoto. Also known as KenKen® and Mathdoku, Calcudoku brings to you over 15,000 unique puzzle grids!
You can play Calcudoku by Razzle Puzzles on your phone and tablet. Enjoy Calcudoku online or in offline mode!

The puzzles offer a fun logic challenge.

This is a good game, just a shame about the ads. Yes it's either watch ads or pay - I get it, but when the advert is over why can't we go back to the game without having to go to ad part 2 and ad part 3? That's when it goes over the line from acceptable necessity to overbearing annoyance. I'm sticking with it for a while, but can't see me keeping it for the long term.

I like the game but it is too easy to accidentally input a number in the wrong square. A simple update that would help a bunch would be to deactivate the grid number selection when the calculator is activated. I find myself accidentally selecting a grid number when I intended to select the calculator numbers. Also, why not just provide the full function built-in calculator rather than the very limited calculator?

It's a great game, I'd happily pay to avoid seeing all the spammy ads, they really ruin the experience.

sorry but 1 ÷ 4 IS NOT 4...its ¼ 🤷♂️🤦♂️
