Collector Trophy in Crazy Machines Elements
Unlock all parts.
How to unlock Collector
Parts are unlocked as you solve all the puzzles in a puzzle pack. To unlock all the parts, you need to solve all the puzzles in the first 5 packs: "Introduction", "Rigid Basics", "Boom, Pow, Poof", "First Elements", and "More Elements". You do not need to collect all the Bonus Nuts in the puzzles to unlock the parts, just solve them. See Perfect Puzzler if you get stuck trying to solve any of the required puzzles.
