Gamification's efficacy is scientifically proven. Game mechanics and game play stimulate the release of four neurotransmitters – dopamine, serotonin, endorphins and oxytocin. Each one, alone, has a positive effect on employee performance. When they are all firing at the same time, they reinforce positive behaviour and regulate one’s ability to learn. They also create a sense of autonomy and competence, and induce feelings of belonging and connection.
