Worst game for ads EVER. 3-5 ads per level. Greedy Greedy people completely ruins the game as ever 30 secs or so an ad pops up. Had 2 30 sec ads on 1 puzzle. DON'T BOTHER. Had support reply about amount of ads, you can pay to get rid of them. So yes they intend 3-5 ads per level. Ruined the game to force people to buy the free ads. Additionally, game won't load or won't load the background or all the pieces
