The objective of the game is to swap one diamond with A adjacent diamond to form a horizontal or vertical chain of three or more diamonds or gems. Click the first diamond and then click the diamond you want to swap it with. If the movement is correct, they will swap and the chained diamonds will disappear.
Bonus points are given when more than three identical diamonds are formed. Sometimes chain reactions, called cascades, are triggered, where chains are formed by the falling gems. Cascades are awarded with bonus points.
