Stars

Stars are a resource exclusive to Scrap Clicker 2 and is the primary measurement of progress in the game. Stars passively increase Scrap production similarly to Golden Scrap.

Purchasing Stars
The player's first 10 Stars are earned or "purchased" by resetting their Barrels, Scrap upgrades, and Golden Scrap. Each Star purchased requires the player to have accumulated a certain amount of Golden Scrap first and multiplies their Scrap production by 10 for each Star owned.

At 5 Stars, the player unlocks the Scrapyard, allowing them to spend Scrap to reduce the Golden Scrap required to purchase Stars. The Scrapyard becomes inaccessible once the player reaches 10 Stars.

Upgrading Stars
Once the player has accumulated 10 Stars, the player can no longer purchase more; instead, at 4 million Golden Scrap (often referred to as "x10.5 Stars"), the player is afforded the ability to individually upgrade and increment the Scrap production multiplier for each Star.

In order to upgrade Stars, the player must spend Golden Scrap, Magnets, and Star Fragments. Because upgrades become more expensive the more a Star is upgraded, it is most cost-effective to upgrade them evenly.
