Calcudoku · Math Logic Puzzles APK 1.37

5 stars: What a nice find! The game is simple to play, once you understand the basics, yet more and more challenging as the puzzle size gets bigger, it is great as a time filler, or to play for longer times, in addition, the adverts are not intrusive, something that other developers should heed - well done.
5 stars: GREAT game, could tweak the UI a bit (namely access the undo button without opening menu) but otherwise a very fun and engaging game. Not sure what other reviewers are talking about, the ads and very NON-intrusive unlike most other apps. Close to perfect!
4 stars: Very Good game. Just one thing I Would like to see is the progression instead of just choosing what table size we like Otherwise it feels like there is no end reward and I am just practicing..apart from that a very good game.
4 stars: Nice game, quite addictive. I would suggest 3 things to make it perfect: 1. A visible timer so you can see if you are close to you best time; 2. A pause button so interruptions don't have to ruin a good time; an 3. maybe rank games easy, medium hard. Some grids are too easy while others can take a very long time.
3 stars: Would be 4 or 5 stars with an undo button. While using the calculator, it's easy to accidentally fill in an actual cell and you won't know which you did. Great game on paper! But this GUI has too many picayune quirks and tics. You can lose by forced gui mistakes easier than by flawed logic. Once they fix the kinks, I would pay for a premium
