The game is fantastic, however after a certain level, the only way to win is to use coins to rearrange the board. They do have the option to watch ads to "earn" coin, however, you have to WIN each game to be able to watch the ad to get said coins. I spent far more $$ then I care to admit buying fake coin with real $$ to win a game to watch an ad that would net me far less coin then I spent to win. See where this is going? A clever black hole to waste real $$. So sad, such a fun game😭
