Set up four sets of three bowling pins across from each other, forming a square or rectangle. The pins within each group are set up one to two feet apart, far enough to make it difficult to knock down more than one at a time. Stand a wedge mat behind each set of pins. The mat and the pins together make up each player’s “battleship,” and the area they are responsible for and need to protect. A few feet in front of each set of pins you may tape a line to the floor the length of the pins; this line gives a tactual cue to each player as to where their area of play is.
The game is played by each player standing in front of their pins to block them, and rolling the goalballs to try and knock down the other players’ pins. The game is started when the instructor rolls out a goalball. After a few minutes a second and third goalball is rolled into play. The instructor announces each time an additional ball is added to the game. When all of a player’s pins are down that player is eliminated from the game and can sit on the floor by the pins. The last player with at least one pin standing wins.
The goalballs must be rolled and not thrown.
A player can leave her pins at any time to retrieve a ball but she can only roll the ball once she is back in front of her pins (this becomes an interesting strategy).
If no one can reach a ball within 15 seconds or if the game is stalled the instructor can move the ball towards the players. The instructor can facilitate the pace of the game by keeping balls in play at his/her discretion.
Assistants and non-players can help with any balls that move beyond the playing area.
