4. Operating Instructions (How to Play)
The objective of each challenge is to insert all remaining screws into the cube so that they are fully screwed in and no part of any screw protrudes from the cube's surface. This often requires careful planning as screws can block each other.
- Choose a Challenge: Refer to the challenge booklet for the starting configuration.
- Place Indicated Screws: Insert the screws shown in the challenge diagram into the cube. These are your starting pieces.
- Fit Remaining Screws: Take the remaining screws and strategically insert them into the empty holes. The key is to find the correct sequence and orientation for each screw.
- Solve the Puzzle: A challenge is successfully completed when all 13 screws are fully inserted into the cube, and no screw is blocking another or protruding.
