How do you get the burnt Joker in Balatro?

The Square Joker is a common Joker which provides a chips bonus that increases by +4 Chips every time you play a hand with only four cards. The four cards played do not have to score and all four can be debuffed.

Balatro has 11 Stickers that can be applied to Jokers or Decks. Stickers can be Stake-based indicating previous wins with this Joker or they can be one of three stickers that have in-run effects. The player cannot manually apply or remove any Stickers.

Burglar is a Joker that increases your hands per round at the cost of losing all discards. This has the added benefit of increasing your income if you can beat the Blind without using all of your hands.
