Kudos are one of Fall Guys' in-game currencies. They can be used to buy items from the in-game shop. You can earn Kudos by performing well in rounds, as a reward during Seasons and external promotions (Prime Gaming). They have the appearance of an purple coin with an large “K” on it.
It was possible to obtain Kudos by buying Kudos Packs (also called Kudos Bundles) with real money, but these packs got permanently removed on 19 May 2022.
