### 3/5 — Can’t save your work??

*2019-08-26*

I have no issue with puzzles themselves, and I can overlook that I can’t check if my entries are right or wrong until the puzzle is solved and that I can’t put in the candidates until I know what goes in a space, but what ticks me off to no end is that my work periodically gets ERASED. It’ll be saved in the app for I’m not sure how long, and then all of a sudden I’ll open it up and ALL of my work is gone, so I literally have not moved on from the first puzzle because I have t keep starting over again!!  Can’t find any other apps that do 25x25 so I just keep doing 16x16s on the app that I like way better. Would be nice if I could just SAVE MY WORK.

### 2/5 — just too hard

*2014-08-26*

need someway to put in readable pencil marks.

### 2/5 — Please make it stop closing!

*2013-12-13*

This app periodically closes out on me. Makes it pretty hard to actually work the puzzles.

### 2/5 — 25 sudoku

*2013-07-06*

Not worth 5 dollars...unless you are an Einstein you will not be able to figure this out.  For 5 dollars the least you could do would include a hints section and a. Verify. That you are on the right trck

### 2/5 — Bg2

*2011-07-05*

Puzzle is great challenge...but I agree with others...VERY FRUSTRATING that you CANNOT ERASE a mistake. Really can mess you up trying to remember where wrong letters are. If this were fixed I would give it a 5 star rating. Please upgrade this version with an eraser!!!

### 1/5 — Frustrated

*2011-03-08*

You can't clear a number that you enter.

### 2/5 — So-so

*2011-01-03*

I had been looking for a sudoku of this size for some time, so I like the 25x25 format and the ability to skip between puzzles without losing my work. It would be helpful to be able to erase a figure that has been entered incorrectly, fill in possibilities in empty squares, and have more definition between boxes.
