After level 90/100, the game is left to chance rather than skill and it ends up costing a lot of coins to not lose your standing. The fortune path reward dropped so you don't get as much coins, even though now hints and help costs more coins. After a while, it stopped offering coin rewards for watching ads and there's no other way to earn them other than winning a level that requires them to win... it started to stress me out more than calm me down so I uninstalled.
