### 3/5 — Good but annoying ads

*2025-12-09, version 7.2*

Uncluttered interface and easy to use. After two games you get the annoying ads which you cannot turn off.

### 1/5 — [chocolate ice cream emoji]

*2025-12-01, version 7.2*

Watching ads to keep the game alive is ok. Watching 3 ads in a row before the game even started is not ok. Wouldn’t recommend.

### 2/5 — Bad, very bad

*2025-10-22, version 7.2*

Too much advertising! And the daily prizes, what are they for? To nothing, why if one plays only in Sudoku, why does he have to laugh daily prizes of other stupid games? It is a non -conceivable and badly done application! Change it or delete it with true taste! Inconceple: the advertising Continuos and continuos…. We can’t play the game without see advertising! A VERY POOR GAME! DELETE IT!
