A professor has taken Om Nom into his lab, and now feeding this little green monster candy requires suction cups, rockets, robotic arms, and water tanks. Cut the Rope: Experiments is a physics puzzle game that builds on the original Cut the Rope formula by stacking eight distinct gadget systems across 200 levels — each level pack introduces a new tool that completely changes how you approach every puzzle. Play this free browser game on PLRun with no download, and discover why the simple act of cutting a rope keeps getting more inventive.
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.
This is where Cut the Rope: Experiments diverges from the original game. The 200 levels are divided into eight packs of 25, and each pack introduces a specific gadget:
Getting Started recaps mechanics from the original — standard ropes, bubbles, and air cushions — to ease you in. Shooting the Candy adds rope guns that shoot a rope toward the candy from any distance, with length depending on how far away the gun fires. Sticky Steps introduces suction cups that anchor ropes to surfaces and can be detached and reattached by tapping, giving you control over where ropes connect. Rocket Science brings in rockets that activate when candy touches them and carry it in a set direction — some can be rotated before launch, and multi-rocket levels create elaborate chain sequences. Bath Time fills levels with water that makes candy float and changes how other objects behave, sometimes requiring you to submerge the candy to reach a deeper path. Handy Candy adds robotic arms you rotate and bend using buttons, then release candy on tap. Ant Hill features ants that carry candy along fixed paths and drop it when you tap or when they reach their endpoint. Bamboo Chutes uses angled chutes that redirect falling candy with a consistent exit speed, enabling loops and velocity resets.
Stars serve as both a scoring system and a progression gate. Each level offers three stars placed in positions that require the candy to travel through a more complex route than the simplest solution. Accumulating stars unlocks bonus levels and later level packs. Hidden photos are also scattered throughout the game — finding them reveals backstory about Om Nom and the Professor. The combination of three-star challenges, hidden collectibles, and eight mechanically distinct packs gives the game a replay structure that extends well beyond a single pass through all 200 stages.
In Sticky Steps levels, many players tap a suction cup to detach the rope and let the candy fall. But the real power is reattaching it. Detach a suction cup, then tap it onto a different surface to create a new rope anchor point. This turns a single rope into a repositionable tool — swing the candy left, reattach higher, swing it right through a star, then cut. Thinking of suction cups as mobile anchors rather than simple release buttons opens up three-star solutions that look impossible at first.
In Rocket Science levels, some rockets can be rotated before the candy touches them. The instinct is to let the candy hit the rocket immediately, but rotating the rocket first to aim it toward a star cluster or toward the next rocket in a chain makes the difference between a one-star and a three-star completion. Always check whether a rocket is rotatable (tap and drag it) before committing to your first cut.
Bath Time levels add water, and candy floats on the surface. Instead of rushing to cut the candy down to Om Nom, let it float for a moment while you reposition other elements. Floating candy is stable and predictable — it won't fall off-screen or hit hazards while it sits on the water line. Use that pause to set up suction cups, aim rockets, or wait for a spider to pass before cutting the candy free for the final drop.
In Ant Hill levels, ants carry candy along a fixed path. Tapping an ant releases the candy mid-journey, and where along the path you tap determines where the candy drops. Map out where the three stars sit relative to the ant's route, then tap at the point where a drop will send the candy through a star before it reaches Om Nom. Releasing too early or too late skips stars you can't go back for.
Many Experiments levels look overwhelming when you see five gadgets, three ropes, and two hazards on screen. Instead of planning from the candy's starting position forward, trace backward from Om Nom: what's the last action that delivers the candy to his mouth? Then what sets up that action? Working backward simplifies complex multi-gadget puzzles into a clear sequence of steps, especially in later packs where chained interactions are the whole puzzle.
Levels with multiple ropes tempt you to slash through everything at once. But each rope serves a purpose — one might be a safety line preventing the candy from falling into spikes, while another positions it near a star. Cut one rope at a time, observe what happens, then decide whether the next cut should happen immediately or after the candy finishes swinging. Sequential cutting is safer and more precise than a frantic slash across the screen.
