This game is great! Every time a new hex spawns an ad pops up, don't want to grind? Watch an ad at the piles or at the upgrade shop. STILL WANT MORE ADS??? Well your in luck... because you'll have one at bottom of screen constantly. Of course you could pay $6 for no ads but who wants to play a game without constant ad interruptions? It is clear that the devs are not cash hungry pigs and really wanted to make a great experience...not. I'm surprised this comment doesn't have an ad. Don't play!!!!
