Cut the Rope: Experiments is an HTML5 physics puzzle game developed by ZeptoLab, the studio behind the entire Cut the Rope series.

Set inside a scientist's laboratory, the game follows the Professor as he studies Om Nom's candy-eating behavior through increasingly elaborate experiments.

The core mechanic stays the same — swipe through ropes to drop candy into Om Nom's mouth — but each of the eight level packs layers on a new gadget that transforms how the candy moves, where it goes, and what you need to manipulate.

What makes Experiments stand out from the original isn't just more levels — it's the expanding toolbox. Suction cups let you reattach ropes wherever you want. Rockets launch candy across the screen. Robotic arms rotate and release objects on your command.

By the later packs, puzzles combine multiple gadget types into chain reactions that require planning several moves ahead.

With 200 levels, up to three stars per stage, and hidden photos to discover, this free online game offers substantial depth for a browser game that loads in seconds. On desktop, click and hold the left mouse button, then drag across a rope to cut it.

On mobile and tablet, swipe your finger across the rope. Beyond cutting, you'll also tap gadgets to activate them — suction cups detach on tap, robotic arms release candy on tap, and ants drop their cargo on tap.

Every interaction beyond rope cutting is a single tap on the relevant object. There's no keyboard input needed. Each level has one goal: deliver the candy to Om Nom.

The candy starts suspended by one or more ropes, and cutting them releases it to swing, drop, or interact with the level's gadgets. Along the path sit up to three stars that you collect by passing the candy through them before it reaches Om Nom.

If the candy falls off-screen, hits a hazard like spikes or an electrical trap, or gets eaten by a spider, the level fails and you restart it. Completing a level requires only that Om Nom gets the candy, but earning all three stars demands a more precise solution.
