A true masterpiece from mechanical puzzle legend Wil Strijbos, the Butterfly Lock Box—formerly known as Pleasure and Pain—is an uncompromising challenge crafted from precision-machined aluminum and steel. This isn't just a puzzle—it’s a personal journey filled with frustration, discovery, and triumph.
The goal may sound simple: Turn the small "LOCK" tube over so it’s right-side up and return all other parts to their original positions. But achieving that goal is anything but simple. No banging, no rotating, no force—just a pure, methodical path of exploration. Every tiny movement matters.
Each box is individually numbered and engraved with its name and Wil Strijbos’ signature, marking it as a collector’s treasure. And in true Wil fashion—no hints, no solutions. Only the bittersweet satisfaction of figuring it out on your own.
A Note from the Designer – Wil Strijbos
➤ History of the Puzzle
The idea for this creation struck me during a trip to Prague on September 13, 2013. The name Pleasure and Pain came later when I realized this puzzle would bring pleasure to a few and probably a good amount of pain to many others.
➤ Why “Butterfly Lock Box”?
If you examine the backside closely, you’ll notice the reason for its new name. Take a moment to look… you'll see it.
➤ The Main Challenge
As mentioned above, your mission is to flip the small “LOCK” tube while returning every other part to its original state. No exceptions. If it’s not exactly as it started—except for the flipped LOCK tube—you’re not finished.
➤ Important Guidelines
-
No force. Ever.
-
No banging.
-
No rotational moves.
-
Pay close attention to movement—slide, turn, and reposition gently.
-
Take your time. There’s no rush. If you hurry, you might forget something... and that’s when the pain kicks in.
➤ “The Medicine”
This final production version includes a small surprise: “The Medicine”—something to ease the pain of mistakes. Only open it if you must.
➤ Bonus Insight
What used to be the “Protection Stick” is now my Business Card.
Also, don’t skip the “About 1mm” picture—it’s very important.
And lastly, “Think of…” (you’ll know what I mean when you get there).
Please try to keep the puzzle original—no shortcuts, no spoilers.
