Flickerball is a group sport played with an American football in similar situations to dodgeball, such as Gym Class/PE classes. It is played in a group of 6 to 40 players who are equally divided into two teams. The teams separate on opposite sides of an area such a gymnasium, parking lot, or field. The game is unstructured in terms of what constitutes or if there will be outs and the length of play nor time-outs. There are many rules and the game is structured most similarly to Ultimate Frisbee. One notable exception is that any shot on goal results in the ball going out of bounds which results in an automatic change of possession. This rule should mitigate wild shots hoping for statistical points. Flickerball was first played at Davidson College in 1951, when it evolved as an alternative to touch football. The name "flickerball" was developed in the mid-1950s and the game is still a traditional game at Davidson College. A newer form of Flickerball commonly called Thunderdome originated in Berwyn, Illinois, at Morton West High School. This Delachian style of Flickerball incorporates many of the same structures of the original game but alters the rules for play. Many US summer camps adapted the game using a dodge ball. The basic setup is as follows: Each team's board is positioned at opposite ends of the field. A boundary line is then placed in play approximately 12 ft. from the board and lies parallel to the board. Rules are that all players can hold the ball for only five seconds and can take a maximum of three steps forward and can either pass or shoot to end the possession. The field length is not standard but the width is usually 1/3 to 1/2 the size of the length and length is about 50 yards for standard size teams. The game begins with players split on each side as is the custom. Players meet at midfield where a jump ball begins the game. Whenever the ball hits the ground the team to touch it last loses possession. The team that gains control must first make a pass laterally or backward. Fouls may be called by a referee or by player agreement if a referee is not present. A foul shot is only given if the player is shooting and if the player misses the attempted shot. shots with fouls that result in a score off the initial shot are not called. A made shot is worth one point if it hits the board and two if it goes through the middle. A missed shot is automatically out of bounds and the other team is given possession unless the shot was tipped by the other team. Normal game times will run about 40 minutes and may or may not have a break at the 20 minute mark. An alternate version of the game, which is commonly played in Wisconsin, follows a different set of rules. After a coin toss and sides are chosen the defending team must send the ball, a throw off of sorts, down to the opposite end of the playing field in which the other team receives. The ball is then passed between team mates with an allotted 3 steps. If the ball crosses into the end zone the offensive team receives one point and the defending team must walk down to the other side. The ball is then thrown off again and again until the game is over. If the ball is dropped at any point in the game, the defending team gains possession. A typical game lasts 30 minutes and consists with teams of 8. This version of the game is a favorite of the Sheboygan North Cross Country team and the Sheboygan Community as a whole.
