Gem rewards don't work DISGUSTING. Spend loads of time installing and playing other games for the rewards, yet they aren't paying out. Got 1 reward out of 4. They owe me over 4000 gems. The 'click here' to report it doesn't work and they ignore emails. Absolutely disgusting. They get the payments from the other games, yet don't pass the rewards on. (yes I did it all right, I've got rewards on many games, but this one isn't paying up) Developer eventually responded. Ran out of text, but rubbish.
