Hanayama cast puzzles are the world's finest brain teasers. The high-quality, cast metal puzzles come in six challenging, Mensa-rated levels of difficulty.
These Level 3 puzzles are considered moderately difficult by most puzzlers.
Galaxy: This puzzle is named after the swirling shape of the Galaxy. It is not that difficult to solve but one becomes totally mesmerized by the pieces that move freely. It is more difficult to put them back together than to take them apart. Take a good look at how the pieces move when taking them apart so you can put them back together again. The theme is "knot."
Coil: It appears like a box-like lump with a hole in it, but is actually comprised of two coiled up virtually identical pieces. You must try to take it apart by sliding and rotating the pieces. Although the pieces are angular in shape, they can be rotated in unexpected ways, making their movements quite intriguing.
