 Players begin at the “Start” square, and must move forward along the wall walk (yellow), not deviating from this path until they reach the Queen's House and are accredited or are instructed to go somewhere by a card.To be accredited at the Queen's House, a player must either surrender a Tower Pass or roll an odd sum.Accreditation is denoted with a flag inserted into the playing piece, and enables a player to move in any direction as they choose (as opposed to only anti-clockwise on the wall walk).
