Double-seven binary-coding hexdominoes is a dominoes-like set that includes 36 tiles (with numbers from 0 to 7) composed of two adjacent hexagons. Instead of the standard pips , this set uses a special concentric binary representation. A central pip equals 1, a small circle equals 2 and a big circle equals 4. This set is the brother of the double-seven binary-coding dominoes set by the same publisher. The tiles are made of 8mm thick laser-cut, engraved and painted black acrylic. It's been devised as a game system. Apart from any dominoes game, you can also play Hexdominimum, Hexdominomega, Hexdominup and Hextra, among others. —description from the publisher
