The English rules are here as a pdf in the Files section ("Marrakech English Instructions").
The diagrams needed to understand them are in the Web Links section ("French Rules - Including Figures Referenced in English Rules").
Finally, the English rules in my Gigamic version include a variant located after the two-player rules. . .
VARIANT: Players take the following actions in order each turn: 1) they throw the dice 2)they move Assam 3) they pay a fine to an opponent (if necessary) 4) they lay one of their own rugs 5) they rotate Assam a quarter turn The next player is forced to move Assam in the direction he is now facing.
