What. The. F. I had to open a locked chest with 5 gems (they are scarce enough). And the 'reward' was being able to... buy gems with REAL money!???? What the actual F! How is this a reward??? I was enjoying the game before that but this is absolutely ridiculous. Why unlock a buy option with in-game premium currency! Dumb, so dumb. Immediately de-installed. Bye bye.
