Level XI uses the components and basic rules of Level X and can be played only in conjunction with the base game. Now your playing pieces can be placed on this supplemental board in addition to the tracks on the main game board. The pieces are not moved here, but they stay where you once placed them - however, you may remove them for other use at any time giving up your position. The playing pieces on the highest spaces of the Level XI board earn you special points at the end of the game – and you can even score for more than one marker. Beware: you may miss a playing piece you placed on the supplemental board for the regular tracks - but if you are too late for it, the best spaces will be occupied there.
