Co do proponowanych zasad backgammona w XV w. mo¿na miec w±tpliwo¶ci. Startowe ustawienie pionków jakie podajesz w instrukcji pojawia sie dopiero w 1822 r. Wcze¶niej nazwa bacgammon nawet nie wystêpuje. Grano zazwyczaj w Tric-Trac'a, z zupe³nie innymi zasadami i z troszkê inn± plansza (specjalne patyczki i dodatkowe dziurki po bokach planszy).
Alfons X: gry z serii "Backgammon" (ale nazwa nie wystêpuje) to:
- Quinze Tablas
- Doze Canes
- Doblet
- Fallas
- Seis, Dos e As
- Emperador
- Medio emperador
- Pareia de entrada
- Cab e quinal
- Todas Tablas
- Laquet
- La buffa cortesa
- Reencontrat
Po¼niej, w dziele Girolamo Cardano "De ludo aliae" (ok. 1500 r.) równie¿ nie ma nazwy backgammon:
- Sperainum
- Speraia
- Speraionum
- Principum ludus
- Tocadigilium Parvum
- Tocadigilium Magnum
- Canis Martius
- Totae Tabulae
- Minoretum Maior
- Minoretum Minor
Nazwa Back-gammon pojawia siê w Wielkiej Brytanii w XVII w. - Willoughby, Cotton; jako jedna z odmian w rodzinie gier:
- Irish
- Back-gammon
- Dub lets
- Ticktack
- Sice-Ace
- Grand TrickTrack
Chyba po raz pierwszy ustawienie pionków pocz±tkowe i zasady jakie znamy dzisiaj pojawiaj± sie w 1822 r. N. Guiton uzywa nazwy Backgammon i prezentuje plansze do tej gry z wspó³czesnym ustawieniem (co ciekawe, wg. rysunku jest to nadal plansza do TricTrac'a).
Podobna nazwa, Baggamon, wystêpuje w korespondencji z 1635 r. u niejakiego Jamesa Howella: w li¶cie uwa¿a i¿ o wiele lepsza od gry baggamon jest Irish.
Wracaj±c do Alfonsa X i gry TODAS TABLAS, poni¿ej zasady (t³um ang. tekstu ksiêgi):
"[f. 77v]
This game they call todas tablas (all tables)
There is another game that they call todas tablas because it is set up spread out through all the
four tables of the board.
And in the two tables that are across from one another on the same side of the bar, one the first
they place five pieces of one colour on the six-point. And of that same [colour] they place two on
the one-point of the other table that is across from it on the same side of the bar, and in that same
table [the other colour] also puts his pieces opposite it [the other colour] as we have said for this.
And in the other two tables that are across the bar from these, on the one-points they put five
pieces of the colour that placed the other
And it is played like this: the one to roll first will play whichever side he wishes bringing the two
pieces from the one-point towards the six-point where he has five pieces. But if some pieces are
taken, they are to be returned to the table where the two pieces are on the one-point. And from
there they are to bring them to the table where the five pieces are on the six-point and from there
to bear them off.
And this game is played with two dice."
