### 3/5 — Game Good, Ads Terrible

*2026-08-24, version 4.4.1*

I play the games from the hard selection, and I don’t mind ads, but 5 times during on the game I was playing was interrupted by ads, very annoying as not only is it time consuming but also loses your train of thought. Do you seriously have to break the game with so many ads?

### 5/5 — Need new puzzle

*2026-08-23, version 4.4.1*

I’m playing everyday ( 5000 play in last 4 month ) but now in expert mode i’m playing last puzzles. Nothing is new and no challenges. 
Please add new puzzle and update it. Thankd you support team.

### 2/5 — Too many ads!

*2026-08-23, version 4.4.1*

I enjoy the game- and the twist on regular Sudoku. But 5-6 ads per game?  Annoying.  Ad to start, 2-3 ads during play, an ad to get to score at the end.  I’m about to delete it.

### 1/5 — ADS!!!

*2026-08-22, version 4.4.1*

Update: I see they’ve been lying for years in review responses saying they were going to fix the ads issue and haven’t done anything as far as I can tell. Too bad because this really is a terrific game.
Original: Love this game and have been playing it for a long time now. There used to be limited ads (one a game if I’m remembering correctly) but now it’s completely out of hand. It ruins your focus trying to play. Gonna start looking for an alternative. It’s a shame.

### 3/5 — Hints are useless

*2026-08-22, version 4.4.1*

When I click the hint button, it just makes my input turn black and doesn’t add any additional number. Useless

### 5/5 — Good game

*2026-08-22, version 4.4.1*

I have played this game for a long time, though I don’t play the challenges. Ads are kept to a minimum, and are usually short. The games are challenging without being so hard they take the enjoyment out of playing.

### 4/5 — ADS - WHEW!!!

*2026-08-21, version 4.4.1*

Way too many ads! Great game, but too many ads!

### 2/5 — Constant Ad popups

*2026-08-21, version 4.4.1*

I absolutely love this game however the app is the problem with the bombardment of Ad’s. Since the slew of ads have no x I have to close the app and go back in several times and then when I click anything the ads start again. The ads are so many it makes it hard to actually work on the game. The ad frustration makes me not want to play.

### 3/5 — Good game but..

*2026-08-20, version 4.4.1*

I’ve just bought this game and I’m enjoying it, but I note that the game colour options are difficult to see, and more variation is required. I’m using the dark mode because it suits me best but the black divider squares line is for the 9 grids is almost invisible. Also it would be useful to ‘quick fill’ the grid with clue numbers as this takes ages and other games I have do this easily. For the price paid, it should be an option. I see this was suggested previously in other feedback but not actioned.

### 5/5 — Fun Sudoko

*2026-08-20, version 4.4.1*

What a creative and fun way to play sudoku! Kudos to the developers!
