### 2/5 — Ads ads ads

*2026-08-24, version 5.6.0*

The gameplay itself isn’t bad, I mean it’s sudoku. But this was advertised to me whilst playing easybrains sudoku.com as haven’t absolutely zero adverts. Since completing the first puzzle I’ve been littered with ads. Every pause, new game, end of game. False advertising

### 3/5 — Works well, but notes count as mistakes

*2026-08-23, version 5.6.0*

Why are notes counting as mistakes? That’s ridiculous, and cheap. The whole point of notes is to avoid mistakes yet you penalize for it and make it very cheaty

### 1/5 — Too many ads

*2026-08-21, version 5.6.0*

I thought I was downloading a game with no ads annnnnnd it’s not.  

There are tons of them and they make the overall experience super unenjoyable.  

Aesthetically, it looks nice.

### 3/5 — Way too many ads

*2026-08-17, version 5.6.0*

Ads are out of control. Made the game unplayable so had to delete.

### 5/5 — Thanks

*2026-08-16, version 5.6.0*

I saw it online and in 5 secs brought back my joy for sudoku

### 5/5 — Tupence

*2026-08-16, version 5.6.0*

It’s great getting my head around this game. I look forward to improving my game.

### 5/5 — Ótimo

*2026-08-13, version 5.5.0*

Muito bom

### 5/5 — Relaxing

*2026-08-13, version 5.5.0*

The game relaxes my at night

### 1/5 — Inaccurate ad

*2026-08-13, version 5.5.0*

THERE IS STILL ADS IN THIS VERSION OF SUDOKU

### 2/5 — Adds still there after buying add free

*2026-08-11, version 5.5.0*

I love the game but the adds kept bothering me so I looked to see if there was ad free and when there was it, I bought it. I immediately went into a game and got an add I thought maybe the game just had to update so I closed it out and reopened it but still adds
