Rebuild a machine with the fewest parts, and prove it never fails.
The Lab's toughest trophy: the smallest machine that still works 10 times out of 10. Shrink it or lose it.
- New skill Making redstone smaller
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 30–45 min
- Ages 13+
What you’ll build
Choose one of your factory machines, count every single part, then build a copy beside it. Remove one part at a time and test, marking anything you can't lose. Find clever swaps, then prove your shrunk machine works every time in front of a judge.
Finish line: Your shrunk machine uses fewer parts than the original and works 10 times out of 10.
Bonus challenge: Challenge someone to remove one more part without breaking it. If they can, they steal the Cup!
You’ll need
- One of your factory machines
