===Additional rules===
[[Robert Charles Bell|R. C. Bell]] developed additional rules, saying those given by Alfonso X, in his opinion, "are not sufficient to play a game".<ref name="Bell vol. 1" />
These extra rules are:
* A piece cannot move backward (e.g., a piece in the middle of an empty board would have five available moves).
* No piece can return to a point it has previously occupied.
* Once a piece has reached the opponent's back row it can only move to capture opposing pieces.
* The game is won when either:
** The opponent has lost all of their pieces.
** None of the opponent's pieces are able to move.

Bell also includes a scoring system for rating games.
