In Gizmos, players take on the role of contestants in the Great Science Fair. They will pluck energy marbles from the innovative plastic Energy Dispenser and use them to construct new Gizmos, adding them to their machines. Players will have to plan ahead as they build, since Gizmos can chain-react off of one-another. As more Gizmos are added, more reactions can trigger, creating some truly epic turns. In the end, the player with the most Victory Points is declared the winner.
