Studs

In LEGO Worlds, similarly to previous LEGO games made by TT Games, LEGO studs ('studs') are currency used for in-game purchases. Players can get studs by interacting with various objects and entities in the game (mainly props and NPC characters and small chests), and use the money to buy previously unlocked characters, creatures and vehicles.

There are three different colors of studs, each with a different value:
 * Silver studs, worth 10 units, common
 * Golden studs, worth 100 units, uncommon but usually comes in money chests
 * Blue studs, worth 1,000 units, rare
 * Purple studs, worth 10,000 units, extremely rare and once found, it is no longer in-game
