Al-Falahia or Al-Falakiya or Kawakib (["stars"] in Persian), requiring seven-sided dice, is a zodiacal gambling game.
Two pages later, (http://games.rengeekcentral.com/F97V.html), there is a seven-player zodiacal Backgammon game.
The Al-Falahia board represents the zodiac; it is round and divided into 12 sectors (houses) marked by the constellations of the zodiac on the outside ring (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces). The central disc is the Earth, and the intermediate rings represent, going from the Earth outward: the Moon (12 spaces), Mercury (2x12), Venus (3x12), the Sun (4x12), Mars (5x12), Jupiter (6x12) and Saturn (7x12). The colours and starting positions of the "luminaries" are:
Moon - Cancer, white
Mercury - Virgo, multicoloured (silver)
Venus - Taurus, violet
Sun - Leo, yellow
Mars - Scorpio, red
Jupiter - Sagittarius, green
Saturn - Aquarius, black
The seven-sided die assigns a luminary to each player (1 - Moon, 7 - Saturn). Next, each player bets (same bid for all players) and throws the die to move his luminary (counter-clockwise).
If the player remains in his starting house, nothing happens.
If he is in conjunction (0°; same house) with another player, he pays him the bid.
In sextile (60°; two houses apart --i.e. one house lies between the players), he wins twice the bid.
Quadrature (90°; three houses apart), he loses three times the bid.
In trine (120°; four signs apart), he wins three times the bid.
In opposition (180°; six houses apart), he loses six times the bid.
One can roughly simulate the seven-sided die by using 2d6 and subtracting 7 from rolls of more than 7:
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6
7 - 7
8 - 1
9 - 2
10 - 3
11 - 4
12 - 5
