After nearly a decade since the release of the original design, we are thrilled to unveil our version of Derek Bosch's Rhombic Maze Burr, affectionately known as RMB.

This captivating puzzle features twelve maze plates and pins that slide across the faces of a rhombic dodecahedron. Your mission: extract the removable exit maze plate from  the intricate labyrinth. With numerous plate configurations possible, this mind-bending challenge can range from a relatively 'simple' 30 moves to a staggering 379 moves.

Collaborating closely with Derek Bosch, we have expanded upon the original design by introducing a second alternative exit plate and an array of exciting new challenges.

Each RMB puzzle includes :

• A 3D printed rhombic frame, consisting of two securely pinned parts made from durable PLA material.
• A collection of 13 distinct maze plates and 12 pin plates, providing a variety of configurations for endless puzzling possibilities.
• Custom-designed brass pins, engineered for effortless insertion and removal by hand. For those with low grip strength or exceptionally slippery fingers, an additional extraction tool is provided.
• A comprehensive challenge booklet boasting a staggering 101 puzzles to conquer, offering an abundance of puzzling entertainment at less than 75 pence per puzzle.

Choose between an orange or green frame to suit your personal preference and style.

Manufacturing the RMB is no easy feat, which is why it has previously been available only in limited quantities. However, we are delighted to announce that we can now offer this brilliant design to a wider audience, ensuring that more puzzle enthusiasts can experience its genius.
