Crowns
Crowns are the win tokens on Bossfeed: you earn one for finishing first on a daily leaderboard or for winning certain games, such as a Surviversus Royale, and they count toward a monthly reward track.
Crowns reward winning, as opposed to EXP, which rewards playing. Your all-time Crown count shows on your profile, along with a list of recent ones.
The monthly track is a simple progress bar with a few stops, and each one unlocks something to keep, starting with a profile icon and then cosmetics. The track resets on the first of the month and the rewards you have unlocked stay yours, so each month is a fresh climb.
Final Boss Fiesta has a related prize, the Boss Crown, given to the winner of a board. It counts as a real Crown when at least two humans took part.
