## What is Sudoku?

Classic Sudoku, multiple difficulty, experience the advanced road from novice to master.

A mathematical puzzle game from Switzerland in the 18th century. You need to infer the numbers in the remaining spaces based on the known numbers on the 9x9 grid.
 
We also adds a note function on the basis of traditional Sudoku. You can use notes to record the number of possible answers to the grid in an uncertain blank square, which helps the deduction process to be smoother. 
At the same time, the minimalist UI interface allows you to focus more on solving puzzles while protecting your eyesight.

Simple numbers, meticulous logic, and the fun of solving problems can all be reflected in Sudoku. Try it out and experience the charm of numbers!

In this update we fixed several minor bugs and made some improvements.We hope you enjoy it! Contact us in case you have feedback or any questions!

### 5/5 — Divertido

*2023-10-04, version 2.7*

Es un juego muy bueno para entretenerse. Me gustaría que tuviera niveles por cada nivel de dificultad. Sin embargo,puedes seleccionar el tipo de partida que te interesa. Hay tres niveles de dificultad y una sección de reto diario.

### 1/5 — Game no longer works

*2023-01-06*

When you open the game everything is in Chinese or Japanese and nothing works. The only think you can click on is the share button.

### 1/5 — Recent month missing

*2022-11-19*

No November available, recent mont missing on daily challenges needs fixed

### 1/5 — Awful ad monster

*2022-10-31*

This is a terrible app. It slows down terribly and key presses back up so you can make mistakes. The ads can lock you out of play so you have to force it to close. 

Deleted it.

### 5/5 — 見やすくて良い

*2022-10-09*

沢山ダウンロードしたけど、見易いと思うし、動きも良い

### 5/5 — 广告问题

*2022-06-05*

我边听音乐边玩，但是时不时因为下方的广告导致音乐不能听，而且重点是广告点叉还关不掉，你弄点广告能理解，但是能不能别搞得音乐也听不了。

### 2/5 — Recycles old puzzles

*2022-03-18*

I tried a few different sudoku apps and this one was my favorite until I noticed it was just feeding me the same puzzles. I kept starting new ones but they’d all look familiar to me. Hoped it was just a glitch but it kept happening so now I’m looking for a new app. :(

### 1/5 — Couldn’t get past startup screen

*2021-11-11*

Images are misleading. There is an advertising banner at the bottom, so not good to let your kids play. Also it looks like you have to click on the banners to go to the next screen to play. 

Lastly, the app will want your location data (for targeted marketing I guess).

### 5/5 — Perfeito

*2021-11-04*

Melhor do que a versão paga do mesmo desenvolvedor.

### 3/5 — Daily Challenge Puzzles broken?

*2021-10-01*

Up until recently the app has worked fine, quite a lot of ads but what else do you expect from a free app these days..

But in the past maybe week and a half, the Daily Challenge Puzzles have broken, always giving the same puzzle for each day :/

The rest of the app is still enjoyable otherwise, but that issue has made the Daily Challenge very.. unchallenging? 😂
