Gold

 is the main currency in BABFT. Gold can be spent on items in the Shop, or buying more save slots.

Gold is awarded based on how far the player travels on the map and how many black walls they pass located at the end of each loaded terrain. The game calculates a player's earnings by adding 8 Gold (10 Gold for Members) for every black wall they pass once. The player will only receive the Gold if they die or successfully reach the treasure. If the player skips every black wall and clicks on the chest to get the gold, the player will instead die. If a player disconnects from the server then the Gold will not be added to their balance, until the player visits the game another time. The maximum amount of Gold that can be earned in a single run is 227 Gold, with both the Member perk and 2x Gold Multiplier Gamepass.
