Do you need some light(er)?

Yes yes it's a lighter...but you cannot burn anything with it, or perhaps your brain :-)

Actually it's a puzzle designed and crafted by Roger D, the famous unknown designer (don't you think-like me-that it's a real pitty that nobody knows him?...), all in metal (the flame is in brass, the core is the metal used for many of his puzzles).

The puzzle is not big, but the size is still satisfaying and the weight is not light (you get the pun?)

Looks impressive, doesn't it?

Anyway, let's continue! When you get a Roger D puzzle, actually you have 2 puzzles: the first puzzle is to understand the goal (it's easy to guess it for R2D2 for example), the second puzzle is to solve your metal puzzle.

For this puzzle, I cannot put a picture of the puzzle in the solved state because it would show you the goal of it.

So what would be the goal? Pushing the flame inside the core? Pulling the flame out of the core? Turning the flame? Or perhaps the goal has nothing to do with the flame?...But once you have solved the puzzle, the goal is obvious of course!

Now the solving experience? Humm let's say it's a difficult puzzle. You do not know the goal, you cannot see the internals...So yes, it's difficult: you can experience some pain to solve it! No external tools are required to solve it, by the way.

You can only hear some things ratling inside: but it's difficult to hear if it's only one thing or many things, where they are, and so on.

The cleverness of this puzzle (despite it's natural beauty) is that the mechanism is not super complex: it's rather simple and definitely very well crafted with good precision.

To conclude: a very nice puzzle to play with. It's also very original. I like the design and the solution (I think I found the "official" solution even if no solution are usually published for these puzzles).
