2007 Game: Rack ‘n Roll

Rack ’n' Roll is a game played on a field as illustrated in the figure above. Two alliances, one red and one blue, composed of three teams each, compete in each match. The object of the game is to attain a higher score than your opponent alliance by placing toroidal game pieces on the central goal structure (the racj), and/or by having robots in their home zone and not in contact with the playing field at the end of the match.

Game Pieces

The game pieces are toroidal tubes made of inflatable plastic. When inflated, each game piece is approximately 32 inches across the outer diameter. Each toroid has an inner diameter of approximately 13 inches, and a height of approximately 9-1/2 inches. There are three types of game pieces used in the game.

Ringers

The “ringers” are made of translucent plastic. They are colored red or blue, with no other identifying markings. Each alliance will start the game with 18 ringers of their color. Nine of the ringers will be located in the alliance zone, and nine of the ringers will be set up against the Alliance Station Wall at the far end of the playing field.

Keepers

The “keepers” are similar to the ringers, except that a broad white band inscribed with the FIRST logotype is imprinted on the outer circumference of the toroid. Each alliance will start the game with three keepers, one per robot. A keeper can only be scored during the autonomous period.

Spoilers

“Spoilers” are similar in size and shape to the other tubes, except that they are made of opaque black plastic. Each alliance will start the game with two spoilers located in their alliance zone.

Scoring

When playing Rack 'n' Roll, points are awarded based on the number and length of horizontal and vertical rows of scored spider legs constructed by the alliance. Alliances build up their scores by hanging game pieces on the spider legs of the rack.

Total point values of scored rows are as follows:

> SINGLETON - 2 points
> ROW of 2 SCORED SPIDER LEGS - 4 points
> ROW of 3 SCORED SPIDER LEGS - 8 points
> ROW of 4 SCORED SPIDER LEGS - 16 points
> ROW of 5 SCORED SPIDER LEGS - 32 points
> ROW of 6 SCORED SPIDER LEGS - 64 points
> ROW of 7 SCORED SPIDER LEGS - 128 points
> ROW of 8 SCORED SPIDER LEGS - 256 points

Note: There is not an additional 2 points for each GAME PIECE in a ROW.
