You are saying that when i invited my friends , i will take 50 master coins But when i done it , only my friends can get the coins It happened 3 times at least
when ı invented my friends to the game ı couldn t get bonus from them
If you mean invite to the same competition then you don't get 50 master coins. Was confused at first too.
You can only get 50 coins when you invite someone to the game, not your competition. Because people could easily farm master coins this way.
