Here we are again! In this week's puzzle your friend has kindly given you her bike to borrow for the weekend so you can go extreme cross-country mountain biking (what an exciting life you lead). Can you unlock this puzzle?
The Problem
Hint 1 - Try thinking about the process; how you will turn the key once it is inserted into the padlock.
Hint 2 - The two bits at the end of key A will prevent it from being able to fit into the keyhole.
Hint 3 - The bit at the end of key C is too long to be able to fit into the keyhole.
The Solution
Both key A and C won't even fit into the keyhole in the first place. Key B however can be inserted into the key halfway and then turned 180 degrees to insert the key the rest of the way. To solve this puzzle you simply had to think about the process of opening the padlock. To see our process of for designing see our Introductory Blogs.
