Crafting

Crafting is a feature in Black Hole Simulator that was added into the game in Update 4. The player can combine 6 of the same planet at the crafting area on Earth to receive a golden version of the planet with 2x the normal multiplier.

You can also combine 6 of the same golden planet (a total of 36 of the same normal planet) to get a single rainbow planet with 2x the gold planets’ multiplier (4x base multiplier).
