This puzzle is a bit complex, so I'll explain the steps:
- The first part is composed of four mini-puzzles. Each of them has a different key to make it a little harder to reach the solution, I think the difficulty increases with each puzzle, but that might be subjective.
- Each puzzle starts from the "left", so there are two arms which are the hints, and the final arm which is the solution. The circle in the center shows how the four puzzles are positioned (the colored arc covers the three arms of each puzzle).
- If a mini-puzzle explicitly shows an operation, then that should be used, otherwise it means the key is to be found elsewhere (you'll love to hate me).
- Once all four puzzles are solved, you should have four separate "clues". The order of the solutions is important for the final solution, but the puzzles can be safely solved in any order as they are independent from each other.
- The riddle is the last part of this complex puzzle, which will help you reach the final solution. Beware of puns and word plays!
- The solution to this question is a single word.
- All of the four solutions are required to reach the final answer, therefore the riddles applies to all of them equally.
The riddle does apply to all four clues equally, but they will not change, while simultaneously changing a bit. The riddle is something "extra".
The riddle and its lines have been separated different stanzas for a reason.
When you get to the end of the riddle, it might help to think out loud.
Four clues you have discovered, to reveal what you seek, but soon they'll be remodeled, to make them even more unique. It takes you to start the sequence, but make sure you're not misled, two of them are sequins, pick the last and go ahead. But then next in line, here comes an addition, an indeed positive sign, in the middle of Charing's station. And finally there's a pair, if they're leading, they don't count, but now you must beware, their position is paramount. Now put them all in order, in the same one that was showed, if everything was proper, you'll decipher the unique code.
notate bene: both the graphic puzzle and the riddle have been created by me. Good luck and have fun.
