Way too many ads. Not only do you get the ads interrupting about every 3rd game but it automatically flips you into Play Store without you clicking on anything, so you have extricate yourself from several levels just to play again. So they get $$ not only from selling boosters but from the myriad of ads they pump your way. The game is fun but the ads make you want to dump it. You can't play more than 3 minutes without that many minutes in forced ads- meaning they send you places you didn't choos
