The core objective of Bejeweled 3 is similar to the previous installments in the series. Players swap any on-screen gem with an adjacent one to form chains of three or more gems of the same color. When this occurs the gems disappear and new randomly generated gems fall from above to fill up the empty space. If these falling gems land into another three-or-more pattern, a chain reaction known as a cascade is caused. Unlike earlier versions, players can now match other gems during a cascade.
