Pages were cached and checked on 14 November 2026. The main rules and history come from pagat.com (the domino section founded with material donated by Joe Celko, and since revised). Britannica Kids (the Students article on dominoes) is used where it helps, and is not treated as the last word when it differs from Pagat. There is no main Encyclopaedia Britannica article on this topic at the usual /topic/dominoes address (that URL returns 404). Wikipedia is not used as a source.

Pagat's history page gives two accounts of the word "domino" on the same page. Its index page writes "Tradionally" for "Traditionally" in the sentence about red spots on Chinese tiles. We follow the wording as written, and do not silently correct either slip in a way that would hide it.

See the fact-check log for the wording of each claim.
