### 1/5 — Poor ipgrade

*2025-11-09*

This game was add free, not any more. I use to enjoy seeing all of the opponents scores now I just see the top and the ones around my score. Now if you fill the last number you can’t remove the same little numbers, so you have to remove them all before placing the last number. I am deleting this game and searching for a better version.

### 5/5 — Play it everyday

*2025-07-12*

Simple straightforward game, love it.

### 1/5 — Multiple solutions found

*2024-10-01*

First tricky puzzle I did proved to have multiple solutions. I would not suggest this app to any true sudoku fan.

### 1/5 — Where is my saved puzzle? Not saved anymore?

*2024-07-10*

Just updated the app. Appreciate the bigger grid but navigation within the app has changed and it’s it’s not user-friendly at all anymore. Can’t find a Support link. Can’t find anyplace in app to comment on the update, which is where you said to go with questions. BIG QUESTION:  Where is my saved puzzle? I got back into the app today and my almost finished puzzle that I’d entered myself is not there anymore?! WTH?!

I used to recommend the app to friends, but can’t do that if I can’t get back in to finish my puzzles!

### 5/5 — Fun and challenging

*2024-05-18*

I play this every morning when I get up. Gets my brain going for the day.

### 1/5 — Latest upgrade removed ad-free

*2024-04-30*

I had ad-free and that disappeared with latest update without any explanation, nor can I restore my status. Not impressed. Had been best version of this game but no more.

### 5/5 — Awesome

*2024-04-17*

It was a great app

### 1/5 — Purchased but still get ads

*2023-12-30*

After buying the app I’m still limited to a couple games before I have to watch an ad.  Why buy it if it still has ads?

### 5/5 — The best !

*2023-12-17*

Plus de 10 ans que je l'utilise et ce soir Astraware m'offre gracieusement la nouvelle version !
Merci

### 1/5 — Update ruined it for me

*2023-06-19*

I played this daily for years, but your updated version has ruined that. I guess I need to find another one
