NavBall will experience its “World Premiere” at the Come Out and Play Festival. This game will bring together GPS gaming, ball and team sports into an action packed 45-minute game. It features 2 teams of 11 players each that will attempt to score as many goals. The “ball” and “goal” are placed on a map of Amsterdam and the players have to get into formation to kick the “ball” at the right angle and speed to make a goal. The players have to move around the city with their GPS enabled phones in order to achieve this.
