The bridge riddle is a tricky logic puzzle that needs you to work out how to escape a horde of zombies in just 17 minutes.
You and your three friends must cross an old bridge but only two may travel at the same time. To make matters worse, your friends travel at different speeds and, as its dark, you must have the lantern with you at all times.
The video stops after the explanation to give you time to think. Can you solve the puzzle?
