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. This Joker cannot receive the Perishable sticker.

Because it scores all cards played certain cards can be upgraded with Hiker that normally would not be due to the hand. This dual combo can act as a strong chip provider for High Card and Pair builds as one can focus on playing the same cards again and again to continuously upgrade them without caring about rank.
