Your mission

Bolt the robot is locked in the lab, and the door has five locks. His battery is almost empty, so he cannot explain anything. Every clue is somewhere in the lab: his battery packs, his cables, the floor, the blueprints, and his own screens. Multiplication is a fast way to count equal groups. 4 rows of 6 is the same as 6 + 6 + 6 + 6, which is 24. Look closely and work together to get him out.

How to crack a lock

  • Pick any lock from the menu at the top. You can solve them in any order.
  • Read every clue before you start. One clue alone is never enough.
  • Use scratch paper. Draw pictures, make lists, and cross things out.
  • Tap the buttons to build your answer. Then press "Try the lock".
  • A lock will not tell you which part is wrong, so be sure before you try.
