About Marble Factory

No installs and no paywalls: Marble Factory is a puzzle game that starts the second you hit play. It is the kind of game where one clever move can untangle a board that looked hopeless. On mobile the game switches to touch controls, so your progress is never tied to a desk. And because it is hosted on LemonArcade, it stays unblocked on school networks and Chromebooks.

How to play Marble Factory

Work out the logic of each layout and solve it before you run out of options. On mobile, the on-screen touch controls take over — tap to interact. A couple of practice runs will teach you more than any instructions.

Tips to get better at Marble Factory

• Work from the constraints first — the parts of the puzzle with the fewest options.
• Scan the whole board before your first move — the obvious play is not always the best one.
• Mistakes are cheap: restarting a level early beats grinding a doomed position.
