It has a "cut here" mechanic to it - you can't decide on the order of slices.
> The Slicer starts by choosing a stack of 11 slices and its corresponding Special. Then the Slicer first flips the Special face up in the center of the table, reading it to the players, and then flips each slice face up in the center of the table. As each slice is flipped, it is placed directly next to the previous slice; the Slicer must continue to place slices in the same direction (clockwise or counterclockwise), with each slice being next to the last. The 11 slices will form a circle, with the last slice being next to the first slice.
> The Slicer then divides the pizza into as many portions as there are players. For instance, if there are four players, the pizza would be divided into four portions. Each portion can have any number of slices, as long as it has at least one slice or the Special (the Special may be either combined with slices or placed by itself as its own portion). When dividing the pizza, the Slicer may not rearrange or change the order of the slices in any way.
Note the 1/11th of a circle makes it so that it is never an easy even cut.
