Password Puzzle Trail
Give it a go here: Puzzle Trail
I have created a puzzle trail where the goal is to get to the end, solving each puzzle to get to the next puzzle. Inspiration for this has come from many sites such as Hack Quest and Project Euler. The puzzles start out fairly easy and get more difficult. So far I have tried to make them all fairly obtainable and if you know how to solve them, they shouldn't take more than a minute to solve.
