I was enjoying this game but will not pay the minimum £6.99 for coin package, absolute rip off, especially as some games are obviously set up to fail unless you use the purchased add ons. Adverts are between every level as well, really tedious, will stick to playing my usual non-ad games Some levels are so buggy, you can see all the tiles left but 3 are missing so impossible to match them all. Also progress chests sometimes don't open when target reached and resets back to 0. Very frustrating
