Calcudoku · Sudoku-like Puzzle

I’m obsessed with this puzzle. I searched for this type of puzzle after playing similar ones on airline mags. It’s great that it offers you a choice of matrix size. It really challenges your brain, especially the 9x9 grid and trying to solve it without using notations or calculators, so you have to keep it in your head. I also enjoy the random mix of math operators, some addition or multiplication only, others mix it up with subtraction and division. You definitely learn the different logical techniques and I feel my aging brain has actually gotten stronger. My one request would be that if you enter a number accidentally in a square that doesn’t conflict with existing numbers, you could remove it without having the loss applied.

I just started playing this site. Before doing so, I had downloaded several other kenken game apps, and was disappointed by every one of them. One app, once EVERY kenken or Sudoku was finished, the screen switched to joining/paying for other apps - one for changing your voice and appearance to those of celebrities. I found no way to exit from these solicitations, and finally had to resort to doing a hard reset every time so that I could them enter the kenken/sudoku app afresh. Also, the app doesn't allow you to correct a mistaken entry, as you would be able to in a book of sudoku or kenken, instead listing mistakes from 1 to 3, and saying that you lost after three mistakes. After about 10 games, I ditched the app. I have, in a matter of a couple of hours filled in love with this kenken app. You can choose from grids of 3 to 9. The grids are challenging but doable, and the add allows you to change responses without being assigned mistakes. You win when you correctly complete the grid. And, MOST IMPORTANTLY, the app does not send you to app sales sites after the completion of every grid. I have just completed one of the 3, 4, 5, and 6 panel grids, and am looking forward to challenging myself with the 7, 8, and 9 grids tomorrow. It is now 1:00 AM, and I must get some sleep before work tomorrow, but I plan to open this app after dinner tomorrow. Although I have yet to play this app a lot, based on my earlier experiences with Sudoku and KenKen apps, I feel this is the best one out there. Pick this KenKen app if you want to enjoy a challenge, while not having to fight the app itself.

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!
