Constant ad interruptions

I got to level 10 and they started interrupting the level with many ads. I lost count, but it was around 7 - in one level. It’s difficult to remember where you left off in your reasoning or even where you had been working on the grid.

I’m deleting it.

ADS!

Way too many ads for what you get. Unless you’re willing to pay to get rid of them, this one is a definite PASS!

Ads are ridiculous

This is a fun game but the amount of ads is ridiculous. There is an ad after every single level. And the game gets interrupted randomly with additional ads. And they charge $15 if you want to remove the ads!

Great game if you like ads

Challenging game that kept me interested. Excessive in-play ads lead to deletion.
