Keep the balls from hitting each other while trying to spot the one true ELVIS ball. Move your mouse over a ball to display a direction menu. Click on the direction you want the ball to move. When you spot the ELVIS ball, double-click to eliminate it. After a few seconds another ball will become ELVIS. Continue until all balls are eliminated. Try not to allow the balls to hit the walls; you lose points and all balls speed up.
Game is loosely based on a computer based activity for air traffic controllers intended to help increase scanning and awareness.
