Stardust Detector Puzzle Solution

Align Numbers to Reach the Target Sum

Stardust Detector Puzzle Example
Before	After

The Stardust Detector Puzzle is solved by rotating the rings such that the numbers add up to reach the target indicated at the bottom of the screen.

Keep in mind that you can only rotate the rings that are indicated on the right side of the screen.

Note: The target sum and numbers are random every time you start up the machine, so you'll have to figure out which numbers (addends) add up yourself!

Teddy Bear Location for the Call of Childhood Side Quest

You can find a teddy bear sitting on a couch on the opposite side of the Stardust Detector Machine. This is part of the Call of Childhood side quest and you can pick it up to hit two birds with one stone!
