### 1/5 — Full screen mid-game ads

*2026-08-15, version 2.17.00*

Full screen ads in the middle of a puzzle cause you to lose your place and break your concentration. Immediate one-star.

### 2/5 — Unfortunate end

*2026-07-25, version 2.15.00*

I used to play this game religiously back when it had few ads, as life got busy I dropped it for a few years. Came back to update it and play again but now it won’t even launch. I checked reviews to see if anyone had similar issues but the most recent complaints are about the excessive ads. If the ad problem is that big then I see no reason to attempt to fix my launching problem. I did try to uninstall and reinstall but that didn’t work. It’s an unfortunate end to an app I enjoyed very much.

### 2/5 — Overrun by ads

*2026-07-18, version 2.15.00*

I’ve used this app for years and recently its user experience has become completely abysmal because of ads! You’re forced to sit through ad after ad with no option to exit and return to the sudoku. Quitting the app multiple times just to clear the ads means I often give up on the sudoku altogether due to the hassle.

### 3/5 — Good but

*2026-07-10, version 2.15.00*

One of the better sudoku apps but wish it had the option to turn off the vibration when you put a wrong number in a cell. Ruins the game knowing you’re playing with guardrails.

### 3/5 — The Ads

*2026-06-28, version 2.15.00*

Good game however the ads are intrusive. Every action has another ad. No paid version available.

### 1/5 — Огромное количество рекламы

*2026-06-27, version 2.15.00*

Рекламы через чур много! И идут одна за другой и не переключаются

### 5/5 — Gamer

*2026-06-06, version 2.14.00*

Game it quick but also challenging. Love it

### 1/5 — Ads

*2026-06-06, version 2.14.00*

There are WAYYYY to many ads. I was wanting to find a new Sudoku game so I got this one and literally every 10 seconds I get an ad pop up. Just going to find a different game at this point.

### 1/5 — Horrible game

*2026-06-05, version 2.14.00*

Terrible game that can’t be deleted. If the developers were half as concerned with producing a quality experience as they were with finding new ways to force adds into the gameplay, they’d be winning global awards.

### 1/5 — Ads ads ads

*2026-05-16, version 2.14.00*

Before even starting my first game I got ad upon ad upon ad, without even a timer showing how long the ads were taking. Finally started my first game, and after 1 SECOND, before I even had a chance to look at the board, more ads! You think that’s the way to keep people interested and use your app? Nope, deleted.
