### 2/5 — Fun killed by long scam adverts

*2026-09-09, version 4.5.0*

I used to enjoy this relaxing game when the adverts were to be trusted & there was a simple exit. The only time that you had to watch the whole advert was a penalty for using all three lives. Even then the adverts were a max of 30 seconds with a one tap exit. 
It seems the game has sold out to scammers with illegal false associations logos of reputable companies. They will really chase you if you given enough information DON’T .
20 seconds is enough to decide if you are interested and we don’t need to be chased around the screen and three or four clicks on false X exits .
i’m looking for an alternative and suggest you do to avoid a scam or worse.
If you are a legit advertiser then your brand is devalued by these scammers.

### 3/5 — Ad riddled all of a sudden

*2026-09-09, version 4.5.0*

I’ve played this app for years, all of a sudden with a new update it’s full of updates and annoying as hell. I just deleted it.

### 2/5 — Great game, BUT….

*2026-09-08, version 4.5.0*

I have returned to doing killer sudoku but have been very disappointed by the amount of adverts that pop up when you place the correct number in the grid! I love doing the expert level, but am having serious doubts as to whether i can use this app any more. I wont be the only one thinking this way. You will lose people unless you address this issue soon.😢

### 2/5 — More ads than play time

*2026-09-02, version 4.5.0*

Unfortunately, you will often spend more time watching ads, than you will playing the game. To the developers, I'll NEVER install an app that you force me to watch for 30 seconds or more. I really enjoy the game, but when you fill in a few numbers , are forced to watch an ad, select a few more numbers, watch an ad, then repeat,  it's time to look for another sudoko game

### 3/5 — Annoying adverts

*2026-09-02, version 4.5.0*

There are far more and far longer advertisements now which is making me think more about stopping using the app…I used to enjoy it

### 3/5 — One adds

*2026-08-30, version 4.5.0*

Over all I like this app. I’m ok with ads, because I don’t want to pay. But when you screw up and get an add, then you do a good move, right after that, and you get another ad. That’s too many. Space them out better.

### 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?

### 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.

### 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

### 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.

### 1/5 — can’t get by the ads

*2026-08-19, version 4.4.1*

can’t play because of ads

## Most critical reviews (10 lowest-rated)

### 1/5 — Holy ads!

*2026-09-08, version 4.5.0*

The ads have gotten exponentially worse recently. It is literally every few minutes to every time you place a number on the board.  I understand ads make money, but this is insane.

### 1/5 — Expert ads

*2026-09-06, version 4.5.0*

I play on expert which makes it take a while before I can find another number to put in. :T that means every time I put in a new number I get an ad. I have to remember what I was doing so I can’t even just watch tv like normal when the ad is playing

### 1/5 — Way to many commercials

*2026-09-06, version 4.5.0*

I like to play the expert without clues but there is a commercial every 2 mins and it makes an enjoyable game totally horrible. Deleting

### 1/5 — Too many adverts

*2026-09-06, version 4.5.0*

Good game but stopping in the middle of a game multiple times is too much. Time to delete me thinks

### 1/5 — Back after 6 months

*2026-09-04, version 4.5.0*

Opened the game for the first time in 6 months, game is still unplayable with the amount of ads they slam down your throat. Still haven't fixed the expert level, it's too easy. It used to be so much harder. Will continue to play elsewhere.

### 1/5 — SEVEN FREAKING ADS IN ONE GAME

*2026-09-04, version 4.5.0*

Edit: I’m deleting this app and I want to make sure you know it’s because of the ridiculous amount of ads interrupting game play. Its ridiculous. 

I’ve played this game forever, and the frequency of ads is getting insane. It’s disruptive to game play and I’m at the point of deleting the app. I just played the daily game and had SEVEN ads. I know you have to monetize, but you’re going to make much less money when you drive us all away.

### 1/5 — Game

*2026-09-03, version 4.5.0*

Good game,but not keeping it cuz too much advertising

### 1/5 — Garbage

*2026-08-30, version 4.5.0*

Puzzles are constantly interrupted to watch ads. My last one was interrupted 10 times.

### 1/5 — EXTREMELY intrusive ads

*2026-08-28, version 4.5.0*

This app used to have short ads between puzzles which was a fine way to support the devs. At some point greed took over and they introduced blocking full screen ads that play after placing every few numbers. Found a pair of numbers? Think again because you’ll have to put the second one in after an ad.

### 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.

*2026-08-31, version 4.5.0*

Too many adds

Best game for teaching logic and number sense. Been playing for over 7 years. Never get bored. Never redundant.

### 5/5 — Great game

*2026-08-28, version 4.5.0*

I have paid for this game and played for several years. I have found it exceedingly reliable and continue to enjoy it.

### 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.

### 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.

### 5/5 — Fun Sudoko
