### 4/5 — Extreme Level 207

*2024-01-14, version 3.1*

What’s up with extreme level 207?  All cells are filled.  There is nothing you can do, yet it shows as unsolved.

### 4/5 — Great selection - almost perfect app

*2022-10-25*

This sudoku app is GREAT and has so many puzzles. Would definitely recommend. There are two things I wish I could change tho. I don’t like having two different number pads. I really wish the layout was closer to the Real Kakuro game, where you can switch between pen and pencil. I think it would make filling in puzzles much faster for me. Also, sometimes after I’ve finished a puzzle, I’ll go back to the menu to start a new one, and the app will freeze up a bit and leave my puzzle as “unfinished” and have erased my last sessions worth of boxes empty. 

If these things were fixed it would EASILY be 5 stars, for now I would still give it 4.5. Check out their other puzzles too!

### 4/5 — Best Version Ever

*2021-09-19*

I've been looking for one that's similar to a puzzle on paper. Most available apps give 3 mistake options and let you know right away when you put the wrong number in the wrong place, which actually helps in solving the puzzle but takes away the realistic style of doing the puzzle. This way is much harder and more realistic. 

I only wish there were options to pick a plain background. The colors can be very distracting.

### 4/5 — Real sudoku

*2021-06-14, version 3.0*

I really like this one but it does freeze at times and I have to reinstall it.

### 5/5 — Great game but it froze!

*2020-03-05, version 3.0*

I love solving the many puzzles, but the game froze on an ad and I can’t open it. Please help!

### 5/5 — Love this game

*2019-03-09*

Great game format , great challenge levels , great mental exercise!

### 4/5 — Very good-challenging

*2017-05-08*

But there's no additional puzzles to purchase when you're done...so that's a bummer...just like their other game, kiruku or whatever, I was so depressed when I finished that

### 5/5 — Deucher Real Sudoku

*2017-02-07*

This is the best Sudoku I've found so far.  It has lots of levels (5). I wonder if this company has other Sudoku as well?

### 5/5 — Mr

*2016-02-01, version 2.4.2*

Very good challenge when you do the hard and tournament. Am very pleased with the download.

### 3/5 — Restore purchases?

*2015-10-01, version 2.4.2*

I would rate this 5 stars if there was a way to restore purchases from my iPad to iPhone. Not a fan of ads and don't want to double pay to remove them.
