Mindball is a two-person game controlled by players’ brain waves in which players compete to control a ball's movement across a table by becoming more relaxed and focused. Mindball is produced by the Swedish Company Interactive Productline. The concept, introduced in 2003, originates from the prototype Brainball which was developed by Smart Studio at The Interactive Institute, also in Sweden.
Similar games have been developed featuring biofeedback, a concept similar to neurofeedback used by Mindball. In 1974, the game Will Ball was developed featuring a premise similar to Mindball though only using biofeedback.
