Obs. [The writer of Ludus Anglicorum (see quot. c. 1330) connects the word with FAIL v.; the game being usually decided by the failure of one of the players to make a throw that would enable him to move. Godef. has two examples of the OF. phrase jouer a la faille, which, though figurative, may contain an allusion to this game.] An obsolete form of Back-gammon.
