User Reviews for Calcudoku · Math Logic Puzzles

Challenging and entertaining

I love this app. It engages my brain so I don’t even feel bad doing it as my “time waster” app (in line at grocery store, in the morning at work when I’m getting warmed up for the day). My recommendation for the next update is to make the calculator clear automatically when you open it (not leave the last number that was there in the space because you end up making a really long number that you didn’t intend to)—just feedback for the developers—I will still use it regardless because I love the app!

Best KenKen I've found

Saves your puzzle when you leave and come back. The built in calculator is a nice touch. Unlimited puzzles. Ads aren't too annoying. Choice of levels. I only wish they let you choose difficulty level in addition to digit level (sometimes I want to chill out with multiplication-only).

One Request To Make It Perfect

This is one of my favorite puzzle games. If I had one request, it would be the ability to choose which operations were used in a puzzle before playing. I find myself constantly opening new game after new game to get a puzzle that just uses addition. I find those to be the most challenging. Perhaps a constant setting where the player could decide just “+-“ or “x+” puzzles, etc. and be able to change it whenever. Hope you make this happen!

Nice Game - Minor improvements needed

I like it a lot better than Mathdoku. It’s user interface is much friendlier. But a couple of enhancements would bring it up to 5 stars.1. Number each game and have a timer. This way you can go back to work on difficult specific games and try to beat your previous times.2. Have an “undo” button to sequentially allow you to go back and make corrections. This, to me, is more useful than the “erase” function (x) - although you should still keep this also. The undo function would allow a ‘permanent’ number to be erased, but your previous pencil marks would then be visible again.

Almost perfect

Compared to the other kenken-esqe puzzle apps I’ve used, this is by far the best. The design is sleek. No overwhelming ads. I love that you use the same number icons for notes and answers, the app designer just needs to have the pencil button highlighted when “note taking” to erase all confusion. I agree with the other reviewer who said it would be nice to have the option to turn off automatic note erasing. When I put in an answer, all my notes in that row and column erase that number. I prefer playing without that feature.

So far, so good

I’ve only played three games, but I like it. Navigating is easy. The puzzles have been challenging, but not impossible. Perhaps in the future I will want more challenge, or I will find that there are deeply challenging puzzles out there. One feature that is very helpful, for larger puzzles that use larger numbers, is the handy calculator. I REALLY like that!

Nice game

Great challenge; I like how the user can adjust the size of the puzzle based on time on hand, state of mind, etcetera. I do wish that the “congratulations/new puzzle” box would not cover the newly completed puzzle. This is one of several apps that I use as cognitive therapy and I’m sure that I’m not the only one who likes to review a “victory” before moving on to the next level. Other than that, (and perhaps bolder lines to delineate cell groups), I find it to be an excellent part of my brain’s daily workout.

Good idea, poorly executed...

This game has a lot of potential, but the controls for the larger puzzles are beyond frustrating! I want to be able to leave notes to myself about possible numbers...I tap on the pencil. Half the time it leaves notes, half the time it puts in an answer. Then as an apparent attempt at idiot proofing it decides to take the answer number (that wasn’t supposed to be there to begin with) out of all other notes, undoing even more work. There may be a way around this but there’s nothing in the directions beyond a very basic how to play message, so that’s no help.

Fun challenge

Fun puzzle game! I like the multiple levels of difficulty. Some of the expert modes I’m still trying to learn how to solve. Sometimes if I have five minutes on the train I’ll do an easy Calcudoku just to bang one out since it’s still fun to play those ones. It’s nice to have the notes available and saved games to keep track of longer games. I love the new stats panel too and the achievements! It’s fun to see my solving times over history on the charts. Please keep the features coming and thank you for this great Calcudoku game!! It reminds me so much of Kenken in the newspapers that I used to play when I was younger. Glad to not have to bring along a paper since I can just play on my phone whenever I want!

Only 1 request

Great free game! No bothersome dynamic graphics on game screen. Between-game ads skip able pretty quickly (and I actually got an add for a site I'll return to for Xmas shopping). One request: hi-light the pencil icon when I'm testing out combos for the squares, and turn off hi-lighting when I tap pencil again to enter my choice. That way I know what mode I'm in and dont make unintended choices. Thanks!
