There are two types of Lucky Draws on Pawns.app. You can enter either of them by trading your gems for Lucky Draw tickets or by winning tickets on the Prize Wheel.
The biggest one is the weekly Lucky Draw with a $1,000 prize pool, shared between eight winners. First place gets $300, and the remaining $700 is split equally between seven more winners, $100 each.
There's also a smaller Lucky Draw every three days. In each of these draws, we randomly pick 25 winners who each get a $2 prize.
From time to time, we also run special Lucky Draws with bigger rewards.
