Just a scam to get us to buy coins
I love quiz games. With other games you will have a theme with multiple questions and need to get majority if the questions right to unlock the next level. With this game, each question is its own level and you need to get it right before you can move on. You only earn 10 coins for every correct answer but you need 100 coins to reveal a letter and 150 to take away unneeded letters. This game is basically just trying to force you to buy coins in order to play on.
