VEX Sack Attack is played on the standard VEX field with 5 inch green sacks and 4 gold bonus sacks. The objective is to score into the floor goals, trough goals, or high goals. Each goal is worth different points based on height. Alliances receive 4 sacks to use as drive control loads. It is important to note that sacks can be obstacles for robots and should be accounted for in design. The trough divides the field but can be passed underneath to get to the other side. This video should help explain more more.
