After you claim your bonus, you will be able to track your bonus in the "bonus tracker" tab located in the lobby menu. Here you will find active bonuses, pending bonuses and more! Any unused free bonus tokens will expire if they aren't played before the set timer expires on that particular bonus. You will be rewarded redeemable sc upon meeting the playthrough requirement for any particular bonus. For more, see the Bonus Tracker tab after claiming your bonus.
