Geometry:
Valentine Cube is a contour cut variation on the classic magic cube puzzle. The highly contoured cuts reveal the shape of four hearts on each side of the cube. However, the centers of the cube are not visible, making Valentine Cube a bit trickier to solve than a normal cube.
Other Items Needed:
Dye: If you want the puzzle to be black, you can save money by dyeing the pieces yourself with a nylon dye such as RIT or Dylon. Or Shapeways can dye the parts for you at an additional cost.
Stickers: Template available in the instructions forum. If you want professionally cut stickers, I recommend Oliver’s Stickers.
Screws: Six 12mm M3 pan head screws required, available in hardware stores or on the web.
Springs: Six springs needed, available in web puzzle shops. I get mine from HK Now Store.
Degree of Difficulty:
Assembly: Easy assembly.
Solving: Moderately difficult to solve.
Playability:
Valentine Cube turns very easily, and the mechanism is stable.
Have fun!
