Educational games are games specifically designed to serve educational purposes or games that have incidental or secondary educational value. While all types of games can be used in an educational setting, educational games are specifically designed to help people learn about particular subjects, expand concepts, reinforce development, understand historical events or cultures, or assist in learning a skill while playing. Game types include boards, cards, and video games. As educators, governments, and parents recognize the psychological need and benefits that gaming has on learning, this educational tool has become mainstream. Games are interactive play that teaches goals, rules, adaptation, and problem-solving interaction, all represented as a story. They fulfill a fundamental need to learn by providing enjoyment, passionate involvement, structure, motivation, ego gratification, adrenaline, creativity, social interaction, and emotion within the game itself while learning takes place.
