Ratings and Reviews

Used to love this game


Now it won’t stop crashing and the ads are excessive. I can’t get through 6 turns without it closing the app. Very frustrating.


Great to horrible

Used to be addicted to this game but the ads have gotten so intrusive lately I've stopped playing. Really disappointed that the developers decided to go the route of yet another failed app.

Edit: ads should come at the end of the game when it is not an interruption (I've consistently had 5-15 pop ups show up in one game, taking me to websites and making the game freeze and it nearly impossible to continue). More people will download your app with resolution. Most of the reviews I have seen are criticism. I have been browsing the store and found multiple, while admittedly not as awesome apps that espouse the sane concept. Please consider this. Don't you see how the ratings for the most recent version have drastically and negatively shifted? As a sincere fan of this (former) app I really hope things change.

Very Simple and makes this great!!!!

I rarely write or play too many games, but OneTwoThree looked fun and challenging so have it a try and very pleased that I did. Very well put together ... Hats off to the devs ... It's one of this that's easy to understand and can provide hours of entertainment!!!!
