This is a relaxing screw puzzle casual game . On each level, multiple interlaced colored plates are fixed by screws, trapping countless colorful balls inside. You need to unscrew bolts in a logical order to remove blocking plates, let the balls fall freely, and match same-colored balls to trigger elimination and clear the stage.
It comes with practical helper props: screwdriver for forced screw removal, chain breaker for unlocking locked plates, timer for extending challenge time, and hammer to blast tricky stuck structures. With hundreds of progressively tricky puzzle levels, fairy-tale themed scene design and satisfying physics-based falling & eliminating feedback, it delivers stress-relieving brain-teasing fun suitable for casual players to kill spare time.
