The Guanlong cube is an intriguing variation of the classic 3 x 3 x 3 puzzle cube. With its irregular fault lines, it offers a unique and challenging experience to puzzle solvers. At first glance, the middle layer consisting of just 2 large triangles may seem like an easy start, but it quickly becomes a source of frustration as the restricted moves limit the possibilities for solving the puzzle. The Guanlong cube requires a different approach and a keen eye for detail to figure out the correct moves and achieve success. It is a great option for experienced puzzle enthusiasts looking for a new challenge to tackle.
