### 2/5 — Please stop asking for reviews

*2026-08-26, version 3.9.8*

I previously rated five stars because I liked having an app for a few bucks with no ads. I liked the app a ton until a few months ago when they started prompting me to rate and review the app after every. single. completed. puzzle. I left 5 star reviews multiple times, but after getting nagged a few hundred times since then, leaving this review in hopes the devs will fix the bug or stop the madness.

### 4/5 — Lots of fun

*2026-08-26, version 3.9.8*

Enjoy playing every day

### 5/5 — Writing

*2026-08-22, version 3.9.8*

This so this review request stops popping up. Avoiding this nonsense is why I coughed up two bucks.

### 5/5 — Sudoku Challenge

*2026-08-21, version 3.9.8*

A great brain challenge and a lesson in patience. I start at Easy and progress through the highest level and then do the level challenge and I start over if I make a mistake.  Lesson is the think through and have patience!

### 1/5 — Meh

*2026-08-18, version 3.9.8*

Game is adequate

### 5/5 — Good game

*2026-08-18, version 3.9.8*

Much fun

### 1/5 — Review

*2026-08-15, version 3.9.8*

I like this Sudoku app, it is my favourite. In my previous rating feedback I gave it five stars. You keep asking me to rate it. Please stop, it is annoying.

### 1/5 — Nightmare to rate

*2026-08-15, version 3.9.8*

Rating nightmare all I wanna do is play the game, but it keeps asking me to rate the game.

### 1/5 — Really bad and I paid for this!

*2026-08-10, version 3.9.8*

This app has little to no functionality. When you complete a number, it doesn’t disappear.  Instead of the pencil staying on until you change it. It goes off every time you touch something different. If you touch a five to see where all the fives are the pencil automatically turns off it also doesn’t tell you if you’ve made a mistake so I went through a game for 30 minutes trying to figure out why it’s not working and there are two threes in the same line.  I would really like to get my money back.  This is the most frustrating thing I’ve ever played.

### 5/5 — Mental reset

*2026-08-09, version 3.9.8*

Sudoku creates a mental reset
