The game can be played at the website jocly.com under the name sultanspiel.
Here it is the rule for promotion that a pawn only can be promoted to a captured piece. Because of that a player who haven't had any pieces captured can't move a pawn to the last rank.
Another rule not mentioned here is that pawns who had made a single step move at their first move may choose between a singlestep move and double step move at their next move.
