What you’ll build
Someone sneaks into the Lab and breaks one small thing in your mega machine. Use the checkpoint bulbs to find the dead stage, hunt down the fault and fix it against the clock. Swap roles, then go for a perfect run of tests.
Finish line: Every sabotage is fixed, there's a fix-time leaderboard and your machine scores 10 out of 10.
Bonus challenge: Move all 5 checkpoint bulbs onto one control panel beside the button, so you can see where the chain stopped at a glance.
You’ll need
- Your mega machine
- A saboteur
- A stopwatch
- Your reset checklist
You choose
- My saboteur's code name
- My bet for my fastest fix: ___ minutes
- The prize for the fastest fixer
Stuck?
- Agree the rules first: one small change per round, nothing deleted for good.
- Check the checkpoint bulbs first. The first one that didn't light shows the dead stage.
- Reset everything between runs, or a leftover cookie or cart can fake a fault.
