# UI:
The game has 6 main UI buttons
1. Friends
Inviting friends is rewarded with diamonds, Bucks and $BIZTY. The more friends the player invites, the higher the reward.
A share of the friends income generated is given back to the referee who invited them.
Sometimes the weekly giveaways are based on the number of friends players invite during the giveaway period.
