User reviews

Ad heavy

It’s a great game, but every one or two moves you have to stop for an ad, which is just far too frequent

Love/ hate

I love the game, I hate this app. If you get the wrong answer there is a minute add. If you get the right answer there is a minute add. The long it takes you the more adds there are. It got so aggravating I deleted it.

Fun but huge problem

I enjoyed the game a lot. But so many ads which is fine for a free game. Except it’s a strategy game that pops up ads mid game. Completely derailing a train of thought. Mid game ads don’t start right away. But was a deal breaker for me.

Ads more than expected

I expected ads but the frequency is too much. Anytime I wait more than a minute to make a move it seems like an ad pops up

Nope

The first thing it does, when you start it for the first time, is ask you to accept their privacy policy regarding the data that they’ll be gathering.
Nope. Uninstalled.
