Marble Factory
NewRun your own marble factory: sort colorful marbles down a 3D production line into their matching boxes before the belt overflows. Free to play in your browser at PlayKovo, no download or sign-up.
Play Marble Factory Online for Free
Marble Factory turns marble sorting into a satisfying physics playground. Release marbles from the trays above and watch real physics carry them onto a constantly spinning conveyor belt, then steer each one into the bottom box that matches its color — each box holds three slots per color. Space runs out fast if you let the belt overflow with nowhere for a marble to go, so quick reflexes and a bit of planning both matter. Levels ramp up steadily, keeping the loop relaxing at first and genuinely challenging as the factory gets busier.
How to play
Release marbles from the top trays and let them fall onto the spinning conveyor belt. Steer each marble into the bottom box matching its color — three slots per color. Don't let the belt overflow with no matching box available, or it's game over.
Controls
Click and drag (or tap and drag on mobile) to steer marbles toward the matching box.
