Just go to "do missions" and select "get votes from Fyber." After that, you'll find a game called "Coin Master." It will ask you to install the app, then confirm and register with Facebook. The game is very easy; you just need to earn lots of coins so you can buy things in the "village shop." When you have 4 stars on all the items, you'll advance to the next village, and your mission will take you to the fourth village. The process is the same each time you go to another village; the price increases, which will take a little longer. And that's it.
Incidentally, not everyone is successful in this mission.
