Tantrix Xtreme Puzzles presented in a mesh bag with 10 tiles

Zome is a completely unique construction 'toy' in that it is easy enough for a 6-year-old to play with, while at the same time letting adult users build truly mind-boggling models. Many of the construction toys available today use magnets to stick together. That’s pretty cool, but unfortunately the weight of the parts restrict building any large or mobile structures. Zome uses precisely constructed pieces that fit together perfectly and offers the ability for kids to expand their objects in up to 61 different dimensions! When completed a Zome built object can be picked up, turned around, and examined from any angle. This kit has 121 pieces and is packaged with a plastic tray for sorting and storing parts. Ages: 6 years +

In the Cube Madness Zome Tool Kit, three different sized cubes seem to spin randomly around a central point... yet there is beauty and order to this madness! Each cube is in golden ratio to the next, and its corners touch the faces of the next -- always in the exact same relative place. The geometry is related to the 5 cubes of the dodecahedron and represents a mysterious link between nature and the human-made world. The Kit contains 83 parts: 25 white nodes, 12 short blue struts, 12 medium blue struts, 12 long blue struts, 10 short yellow struts, 8 medium yellow struts, and 4 long yellow struts, plus detailed instructions. Ages: 6 years +

Tantrix Xtreme is a more fiendish alternative to the Discovery, mainly aimed at keen puzzlers or experienced Tantrix players. It contains eight Discovery-type loop puzzles with an extra twist: no colour clue is given for each level. Two new tricky pyramid puzzles are added that provide an even greater challenge. Your aim is to build loops of various shapes and sizes starting with just three tiles. Each new tile added gives you a different and more challenging puzzle.
