Lots of ads. Annoying full screen ads that you can't get out of. Ads that block the swipe back functionality so you can't even use your phone when the ad is playing. Then when you're back in the game, you guys pummelled with another ad immediately. Don't think of the game as one where you match shapes, think of it as one where you have to dodge ads to get some game time. If that's your thing, then this game is for you.
