Solve this marvelous masterpiece and you'll enjoy a magnificent aha moment that might just make you say, "Mmmm." The 4M puzzle includes four M-shaped pieces, a box, and a lid. Your first challenge is to fit three of the pieces into the box with the lid placed flat on top. You'll notice there is a protrusion on the underside of the lid that makes this task a bit more challenging. But to really appreciate the brilliant elegance of this packing puzzle, you'll need to figure out the trick to fitting all four M pieces into the box with the lid flat on top.
A wonderful puzzle for both novices and experts, 15-20 minutes of experimentation will be rewarded with a genuinely satisfying epiphany, the likes of which are very rare in the world of puzzles and nearly nonexistent in the messy realm of real-world problem-solving...
