Turnabout

Turnabout, known in Japan as Migi Hidari (U-SA) is a puzzle video game developed by Artdink for the PlayStation. The player's objective is to rotate the stage's screen 90 degrees clockwise or counterclockwise until colored balls fall and touch other balls or stationary blocks of the same color, causing the matched objects to disappear. The round is complete when all colored objects have been removed.
