Assist System explained

[TheOtherGuy]

The simplest way to explain the assist rule is to literally use their definition:

ASSIST: an event worth bonus points that occurs when a unique ALLIANCE ROBOT POSSESSES the ALLIANCE’S BALL in a unique ZONE (i.e. red, white, or blue ZONE) during a CYCLE.

In order to have one assist, you need one robot to posses the ball in one unique zone. To have two assists, you need two unique robots possessing the ball in two unique zones. For three assists, three unique robots possessing the ball in three unique zones.
