Free to play, Pay to Win (or rather keep playing) The creators have basically made it impossible to continually play without paying. In the adventure mode, you MUST get 3 stars to earn coins (mind you, it's 1000 to play and you only net 75-150 coins after winning 3 stars) 2 stars result in a 400 coin loss. In live games, you must get first place to win any coins as well, but the profit margin is higher (1.5k to play 3k reward), but once again anything under results in lost coins.
