The plinths for the ball game in the Chichén Itzá area may not be moved. However, on the game field that the teams have been given and that is also used in the competitions, the two pink areas have a different shape than in the task document:
In the tasks they are simply squares, on the game field these squares also have “arms”.

The shape on the game field is relevant for solving this subtask, i.e. even if a Sochel only touches the pink arm and no longer the square, it still scores full points.
