Why a Domino?a little domino history.... Dominoes evolved from dice. In fact, the numbers in a standard double six domino set represent all the rolls of two six-sided dice. A set of Chinese Dominoes contains all the possible combinations (including duplicates). European dominoes use only the unique rolls (and add in the blanks). The word "domino" appears to have derived from the traditional appearance of the tiles - black dots on a white background - which is reminiscent of a "domino" (a kind of hood) worn by Christian priests. I have a huge affection for dominoes! Remember, I found an old...moldy...used...and weathered set of layered Dominoes on a trip across the pond. The "dot" side appears to be a 'celluloid-ish' (have no idea what it is) type of material...and the back layer is a painted black wood. There is true imperfections on each one. (this being a major attraction to me). I don't necessarily play dominoes...but, I do wear them!
