### 4/5 — Great overall but not optimal for one-hand use

*2026-08-21*

Would be nice if the next cell was automatically selected after entering a value in the previous cell. Looking for any kind of auto cell select really because it’s a lot of tapping up/down the screen. Maybe even having the numbers to the side of the puzzle would help for easier selection. Other than that, app is great overall for playing sudoku without ads or interruption and even offline.

### 5/5 — Hate the new hints

*2026-08-15*

Hate the new hints

**Developer response:** Thanks for your reivew. You can switch back to the old hints anytime from Settings by turning off Smart Hints

### 5/5 — Review

*2026-05-16*

Good version of sudoku app

### 4/5 — Challenging and no ADs

*2026-04-11*

It was great not being interrupted by ads. It was fun and the jigsaw sudoku was a neat challenge.

### 5/5 — Great!

*2026-03-29*

👍

### 4/5 — pretty neat!

*2026-03-05*

i wish the correct answers locked in so you couldn’t accidentally change them. also, sometimes ALL of a specific number won’t be highlighted when you select one of them, which is unfortunate. otherwise, no complaints.

### 4/5 — pretty neat!

*2026-02-24*

fun game, i wish the correct answers locked in so you couldn’t accidentally change them but otherwise no complaints

### 3/5 — Wrong logic

*2026-01-01*

I was hopeful this would be a good app to replace a great one that has not been updated. However that is not to be. 

Here, you select a square (out of the 81 available) and then choose a number as your entry. That’s backwards. 

It is dramatically better to choose the number you want to try and have that highlight all the instances of that number in the puzzle, and then pick a square for that number. 

I need to find another Sudoku.

### 5/5 — Simple but no ads

*2025-10-30*

It’s great. It has no ads, I can just keep playing till I’m done doing the puzzle. While I also like to unlock things, have different backgrounds and compete in the tournaments; having a sudoku app where it’s just sudoku is very refreshing and satisfying.

### 5/5 — Fun and ad free!

*2025-09-29*

I’ve never tried Jigsaw Sudoku before now. It’s really a nice twist on the game. I like this app. It’s a good time sink. 😊
