Playing games increases dopamine release in the brain. It basically functions as a neurotransmitter – a chemical released by nerve cells to send signals to other nerve cells. The brain includes several distinct dopamine systems, one of which plays a major role in reward-motivated behavior. Most types of reward increase the level of dopamine in the brain.

We know games are capable of changing people’s behavior for the better. They work for lifestyle intervention, therapy, rehabilitation and health care professional training.
