hist-games: Hazard 2 vs 3 dice?

[Chas]

Someone recently gave me their own translation of some of the dice games
from Alphonso X's Book of Games. What the MS calls Hazard appears to be
a 3-dice game (see below) since the highest roll is an 18. Anyone know
the source for the earliest description of 2-dice Hazard (which seems to
be what most modern books describe).

The game called Hazard

There is another dice game called Hazard and it is played like this:if
the first player rolls 15, 16, 17, 18 or their opposites 6, 5, 4, or 3
then he wins. Any one of these numbers, rolled in any of the
combinations described for the games above, is called Hazard. 

If the first player does not roll a Hazard and rolls more than six but
less than fifteen, in any of the combinations described for the games
above, and then another player rolls a Hazard that is Re-Hazard and the
first player loses. 

If the second player does not roll Hazard then its Re-Hazard again and
he takes his number, one of those above 6 and below 15, however it is
rolled. Then they take turns rolling until one rolls a Hazard or his own
Re-Hazard and wins or the other’s Re-Hazard and loses. If they both roll
the same first number, that is called Evens and neither wins until that
same number is rolled again, in the combinations described above.

My interpretation of the above

The first player wins if he rolls a 15, 16, 17, 18 (the four highest
possible scores) or their opposites 6, 5, 4, or  3 (the four lowest
possible scores). These numbers, are called “Hazards”. If the first
player does not roll a Hazard, and second player, does roll a Hazard the
second player wins.

If the neither player rolls a Hazard on his first try, the scores they
rolled are called “Re-hazard” and become new goals, or nicks. The player
take turns continuing to roll the dice until one othem wins by rolling a
Hazard, or his own Re-Hazard, or rolls his opponent’s Re-Hazard and
loses. If they both roll the same first number, it was called “Evens”
and the first player to roll that number again wins.
