This is our Curvy Copter cube. There are also helicopter or copter puzzles, but these have straight lines instead of curves. It looks a bit complicated, but it's not that hard to solve. The rotation center for Copter puzzles is in the middle of any edge, unlike a corner or the middle of a side; and through the design, the Curvy Copter adds a few more places to solve than the regular Copter. The Curvy Copter Puzzle Cube is a classic 12-axis hexahedron cube, as it deforms after scrambling, making it very interesting. The edge only changes in color direction, but not in position. Each wedge can be rotated in 60-degree increments. And that makes it a completely different puzzle than expected. This is a very special magic cube, which gives you a whole new gameplay and gaming experience. It's pretty cool. The restoration steps are complicated, so some patience is required to learn. But we believe you can do it. A unique toy gift for anyone who loves puzzles, especially for professional players, add it to your cart now.
