Kudos can be earned in-game for free by taking part and being part of the gameplay. You also have the option to purchase extra Kudos via the PlayStation Store or Steam!
Crowns can be earned by winning shows and cannot be purchased. You can also earn Crown Shards by playing different show types and completing Challenges to make a whole Crown. You'll need 60 shards to make a Crown!
Crowns and Kudos can be used in the Store to buy customisations like costumes and emotes.
