It is the constant and unrelenting purchase of coins that is needed to even play one or two songs to guess. For petes sake front players with 1000 coins if making one letter correction costs 90. And forget if you accidentally tap the wrong letter, like no one ever does that. Cant even learn how this game works on the very first tutorial song before coins are needed. Do not waste your time or money on this terrible app. You would have to pay like $5 every minute or so just to get through a couple rounds. Huge rip off.
