What 🁢 means
It shows a domino with its pips out of view.
A blank tile has its empty face visible; this sign shows the reverse. Its vertical direction records how the tile sits in the layout.
When were Chinese dominoes first recorded?
Chinese dominoes are documented by the twelfth century.
That is an early written reference, not a confirmed invention date. European double-six dominoes caught on in the eighteenth century.
A report from 1893 describes Chinese fortune-telling with domino combinations.
