### 4/5 — Great Game

*2023-08-20*

i actually grew up watching my grandma play this game, calling her weird or crazy bc all she was doing was putting numbers in random spaces and scribbling out the wrong numbers here or there. little did i know i’d been older and more understanding of the puzzles and grow a strong liking towards it. i’ve downloaded multiple suduko apps but non compare to this one. i love it.

### 5/5 — Love this Game

*2023-05-07*

This is my favorite game to play while waiting on the kids, or sitting in the doctors office.   Only drawback is that I wish the numbers at the bottom, weren’t so closely together. I have big fingers and hit the wrong numbers a lot .  Suggestion:  make them bigger , or space them further away from each other.  That would be great.

### 4/5 — Please Fix!

*2023-02-14*

I love this Sudoku and play it every day. I have had the app for several years. My one complaint is that there is no way to retrieve a puzzle if I accidentally touch the “next” button. I find this super frustrating as it usually happens when I am deeply into a puzzle. Please fix this for klutzes like me!

### 5/5 — Ads

*2022-11-20, version 1.11*

Adds are annoying

### 5/5 — Great Learning Supplement

*2022-09-24, version 1.11*

Great app for help getting my first grader interested in learning vocabulary and deductive reasoning. I recommend sitting along side your young one and doing multiple rounds as a team until they start showing that they can do it on their own.

### 4/5 — I enjoy

*2022-06-07, version 1.11*

I’ve been playing this now for almost a month I believe, normally stoned 😂 but the multiple types of games and the fact that if you finish within a certain time frame gives you so many stars..I’ll also throw in there wasn’t as many ads in there like I thought it would be

### 4/5 — No time

*2022-03-26, version 1.11*

I really enjoy playing these games especially Sudoku. But their is no time in my day to play them as much as I would like to.

### 3/5 — Quite nice but…

*2022-03-16, version 1.11*

This app looks good and works well. But it would be really great to have boxes filled in automatically when only one outstanding number in a set (within a larger box or in a row) remains. It seems like a waste of time to do everything manually.

### 5/5 — 100% recommend it

*2021-12-07, version 1.11*

I love this game it’s the only one I play . I had it in my past cell and started new with this one.

### 5/5 — Awesome Game

*2021-11-19, version 1.11*

This is a great game, it definitely tests your ability by using strategy. I would highly recommend anyone to download it.
