The aim of ABRAXIS is to form closed geometrical or symmetrical figures with the different irregular shaped elements. It does not matter how many AXIS you use, but the greater the number, the more difficult it is. Try it out by constructing figures that are illustrated in the instruction book, or you can even form a 4x4x4 cuboid or make a letter of the alphabet or some other imaginary form. You can even play it as a 2+ player game if you have other people with their own set of ABRAXIS. (It help if they are different colors.) A great spatial awareness puzzle that will test your ability to manipulate shapes as you build. Consists of 13 green pieces.
