Vivid Bucks can be used to enter contests. They look like this in the app:
They have no cash value but result in real money payouts similar to those with cash entries.
Vivid Bucks are awarded as part of promotions, competitions, and getting cash entries partially correct. If you get any part of your cash entry right, you win. We do the best we can to make it rain.
Vivid Bucks will be reclaimed if they go unused for a period of more than 30 days.
