According to Mario Arru, one of the most talented Skyball players, "Skyball is very demanding sport where outstanding physical abilities must be combined with mental sharpness and highly synchronized group strategies in order to beat not only the opposite team, but also the hazardous field where action takes place".

Rules

There are two teams, each one composed of three players, and every team tries to achieve as many points as possible.

Points can be obtained in two different ways, i.e., by scoring a goal and by penalization of the opposite team. Points due to scoring a goal follow the simple equation:

n² + fx

where n is the number of times the ball has been touched by the scoring team, and fx is a parameter that depends on the ball's speed by the time it reaches the goal. Penalization points are always given by the electronic referee with messages such as

Penalization(TEAM) = 10Points

where TEAM is a variable that can take values HOME or AWAY. However, a coach can challenge the decision of the electronic referee by writing in his terminal the following command:

Challenge = TRUE

In this case, it is up to the public to digit the degree of challenge acceptance of the challenge, e.g,:

Spectator(817).Acceptance = 0.7

where 817 is the number of a given spectator and Acceptance an attribute that can take real values from -0.2 to 1. Total acceptance will be calculated by using Mauro's Algorithm:

The Field

The Skyball field consists of three concentric rings, each one of them rotating in the opposite direction than the one(s) next to them. Speed of rotation varies according to the diameter of the ring, being faster rings the ones having smaller diameters.

According to recent studies, goal probability increases as the aiming player approaches a fastest area, which are closer to the goal area. However, being too close to the goal area slightly reduces goal probability from its maximum (0.31), achieved at the orange zone.
