User Reviews

Users praise Andoku Calcudoku for its addictive and challenging puzzles, silent and reasonable ads, elegant interface, and helpful hints. Common issues include bugs like incorrect number ranges, inconvenient hint button placement, lack of features such as dark mode and autocalc, automatic pencil mark removal, and puzzle reset bugs. Overall, it is highly recommended, especially for math enthusiasts, with excellent design and thoughtful ad handling.

Pros

Addictive and excellent puzzle gameplay with varying difficulty levels.
Ad experience is well-handled: silent by default, reasonable frequency, and can be muted.
Interface and design are user-friendly and elegant, including features like multiple cell selection and clear visuals.
Built-in help/hints to teach solving techniques, suitable for both beginners and advanced players.
Great value for the price with offline play and ad-free options.

Cons

Issues with number range in certain puzzle sizes (e.g., 7x7 puzzle using digits 0-6 instead of 1-7).
The hint button placement near the calculator causes accidental hint usage.
Lack of some expected features found in other related apps like autocalculation or dark mode.
Automatic pencil mark removal frustrates some users who want to use custom solving techniques.
Bug where resetting and quitting a puzzle immediately causes it to disappear from the roster with no resume option.

Recent reviews

Love the game. Just started playing it today and am playing 7x7, but the numbers at the bottom are 0-6 (rather than 1-7) Need this BUG fixed please...

Been playing for years. I love how the ads are silent by default in this game so I can play it while I fall asleep with calming music on. The ads are so reasonable too. And the game is great. Some more challenging than others. Only thing I wish they had was a dark view so it doesn't hurt my eyes/sleep as much. I play almost every night while winding down to quiet my mind of all the fuss of the day.
