### 1/5 — Perché esistono app così brutte ?

*2019-06-02, version 6.01*

Perché esistono app così brutte ?

### 1/5 — Pubblicità invasiva

*2018-11-10, version 6.01*

App esteticamente carina, ma uguale a tante altre ma la cosa peggiore è la pubblicità che appare mentre uno sta giocando a tutto schermo facendo completamente comparire il gioco !!
Assurdo.

### 1/5 — Popup in every turn

*2018-01-05*

How can you focus on the number when the ads kicks in every turn?

### 1/5 — Bad Game Design

*2014-07-25*

I like the concept, however, the game screen on an iPhone is hard to use.  The options screen has such small print it is hard to read.  Also, there is no easy way to remove a number once entered.  The Sudoku games created aren't symmetric.

Then the ads kick in every few turns, so playing a game is very annoying!  There isn't even a purchase option for "Remove Ads".

### 1/5 — Nope

*2013-04-28*

Goat pop up ads seconds into the game and non retina graphics. No thank you.

### 2/5 — Surprise ad

*2019-05-17*

I found this app on a trusted tech website as an app that was normally $2.99 but was free today only. I’m so happy I didn’t pay for it. It’s got ads and will pop up during the gameplay. 

Interface is interesting.

### 5/5 — Great game

*2014-03-26*

Love the chalkboard design. Music is soothing. The degrees of difficulty make it challenging or effortless.

### 5/5 — Egreat

*2013-05-09*

Great app, fun to play, no pop up ad. problem
