Customer Reviews

Have to pay for levels above medium.....

I love Sudoku and all the varieties the puzzle comes in. I downloaded this app because it appeared to have a variety of levels including my fave Mega Sudoku. However, once I opened the app I was disappointed to see the only levels avail are easy or medium. You have to upgrade (pay) to unlock the games they feature in their pics. Not koo y'all!! Other than that I gave 2 stars because the medium level games took a little longer than I expected to complete and I like that it has the option to note multiple numbers in a square until you decide on your final answer. But I really think I am going to uninstall this game and search for one that has access to many levels w/o having to pay for it!!

Note to Developers: You should consider some sort of trial to access the higher levels. My issue isn't the price of the upgrade, it's not knowing if I will like the upgraded levels and games. Allow us to try and then buy!!


Like the notes capability, hate the assumptions.

I like that the app allows the user to make notes, but I absolutely HATE that there is some kind of an underlying assumption that puts numbers into cells before I am ready (which then causes my notes to get wiped from other cells!) This function leads me down the wrong path half. I don't want the app to automatically remove my notes. I want to do that myself. Also, toggling is a royal pain. Sometimes I accidentally leave the notes button off between cells and have to immediately go back and redo. If the app has made edits for me while I am doing that I can't tell the difference between what I've done and what the app did for me. Very frustrating. Getting a different Sudoku app because I can't stand it.

Simple, enjoyable, free

I am seriously considering paying for the enhanced version. This version has uninvasive ads and only has up to medium difficulty. I do not use notes because I enjoy the extra challenge.

My experience has been enjoyable, my only wish is that with a simple in app purchase I could upgrade rather than downloading an additional enhanced up. But that's obviously a minor inconvenience.
