Dominoes 49 glyphs, the same combinations vertically for another 49, and also a horizontal and a vertical "back" for a total of 100 glyphs. In this arrangement, both orientations are present: horizontally both tiles [1|6] and [6|1] exist, while a regular game set only has one such tile. The Unicode range for dominoes is U+1F030–U+1F09F. The naming pattern in Unicode is, by example, . Few fonts are known to support these glyphs. While the complete domino set has only 28 tiles, for printing layout reasons, the Unicode set needs both horizontal and vertical forms for each tile, plus the 01-03 (plain)
Chinese dominoes to 14th centuries have survived. Unlike most modern tiles they are white with black and red pips. During the Qing dynasty (1644-1912), the suits known as "Chinese" and "barbarian" were renamed to "civil" and "military" respectively to avoid offending the ruling Manchus.

It is possible that these were the types of dominoes that made it to Europe the following century. Each tile pattern in the Chinese domino set is made up of the outcome of
