I remember a video of Flothaboss asking for a really hard combo that is very hard to win when used in a raid. Many commented and one won and got 2000 gems as reward. Similar questions are also asked by RR2 in our facebook page. The answer they think is really good is elected and they are rewarded with gems. But many players miss these events. Such questions can be implemented on ingame. Not outside the game. By doing so many people won’t miss such opportunities. Just add such questions in the game announcements. And everyone can participate and enjoy gems.
