If you want one physics puzzle game, make it Cut the Rope: it’s free, rated 4+, has 425 levels and plays offline. For something you build rather than solve, Poly Bridge 3 (free) and World of Goo 2 ($9.99, no ads) are the best on mobile.

Solve-the-puzzle games #
Cut the Rope: Physics Puzzle #
Still the benchmark. You cut ropes so a candy swings, drops and bounces into the mouth of Om Nom, a small green monster with no patience. The current version lists 425 levels across 17 themed boxes, each introducing something new: bouncy platforms, teleporting hats, steam valves, gravity switches. Its store page explicitly promises you can “Play offline anywhere, anytime.”
It’s free, and some items can be bought, “including randomised items,” according to its own description.
Wrong for you if: you want long, open-ended puzzles. These are short and precise by design. More in this style: games like Cut the Rope.
Brain It On! #
You draw shapes with your finger. They become real objects that fall, roll and push. The goal might be tipping a ball into a cup or getting two boxes onto a platform, and almost every puzzle has more than one answer, which is the appeal. Free, rated 4+, and still updated as of July 2026.
Wrong for you if: you want a story or progression. It’s a list of problems, and that’s it.
Shatterbrain #
The same developer’s follow-up, built around breaking things rather than balancing them. Same drawing mechanic, different goal.
Wrong for you if: you already have Brain It On! and want something genuinely different. These two are close cousins.
Where’s My Water? #
Disney’s channel-digging puzzler, where you carve through dirt to route water to Swampy’s shower. The original costs $1.99 and hasn’t been updated since July 2023. The free sequel, Where’s My Water? 2, is now published by Kongregate and was updated in August 2025.
Wrong for you if: you want a game that’s actively maintained. Buy the original only if you’re on a device it still supports.
Build-something games #
Poly Bridge 3 #
Dry Cactus’s bridge builder, free since September 2024 and updated in August 2026. You have a budget and some materials, and the fun is watching your bridge sag, snap or somehow hold as a truck crosses it. It’s the best-supported physics builder on mobile right now.
Wrong for you if: you get frustrated by trial and error. Bridges fail repeatedly before they work, and that’s the loop.
Bridge Constructor #
The older, gentler take, $0.99 on iOS and still getting updates in 2026. There’s also a free Bridge Constructor Playground with no budget pressure, which is a better starting point for younger players.
Wrong for you if: you want the newer physics and level design of Poly Bridge 3.
World of Goo 2 #
The sequel to the 2008 classic, $9.99 on the App Store since April 2025. You drag living goo balls into towers and bridges, and the sequel adds liquid you route through the level. Five chapters, more than 60 levels, no ads and no purchases.
There’s also World of Goo Remastered, published by Netflix and free on the App Store, but its description says it’s “Available exclusively for Netflix members,” so it needs a Netflix subscription rather than a payment.
Wrong for you if: you object to paying up front. It’s the most expensive game here by a distance, and also the only one with no monetization inside it.
Bad Piggies #
Rovio’s spin-off, where you assemble a vehicle from motors, wings, fans and bottle rockets and try to get a pig to the goal without it falling apart. More than 200 levels, plus 40 more that open when you three-star enough of them.
Wrong for you if: you want steady progress. Half the game is a contraption exploding on the launch ramp. Its last update was November 2024.
Destruction games #
Smash Hit #
You move forward through a glass dimension and throw metal balls at anything in your way. It’s less a puzzle than a rhythm test, but the glass physics are some of the most satisfying on a phone, and it’s free and rated 4+.
Wrong for you if: you want to think. This one’s about reaction time.
Kitty Kaboom #
Kitty Kaboom is ours, so judge it accordingly. It’s a slingshot game rather than a hand-drawn puzzler: you drag back, a line of dots previews the arc, and you launch cats at robot vacuums standing on structures made of cardboard, wood, glass, brick, metal, soap and battery packs. Each material behaves differently, and the puzzle is working out which piece is holding everything up.
The part that makes it a puzzle rather than a shooting gallery is the tap. Six of the seven cats have a power you trigger mid-flight: an explosion, a split into three kittens, a straight-down slam, a sonic yowl that shatters glass and dazes robots, a rocket dash, and a magnet that pulls metal and robots. Three stars are awarded for clearing a level with half your cats or fewer, so the game scores you on the elegance of your solution rather than the size of the explosion.
Free, 60 levels, a daily challenge, no in-app purchases, and no account.
Wrong for you if: you dislike ads. A banner stays on screen during play and a full-screen ad appears after roughly every second level result.
How the physics actually works #
All of these games run the same basic loop: advance time by about 1/60 of a second, apply gravity, move everything, find overlaps, push them apart with the right amount of bounce and friction, then draw the result. The differences you feel between them come from a handful of numbers per object, mostly density, friction and bounciness. We take that apart in how physics games work, and the bounce number specifically in why some things bounce more.
Frequently asked questions #
What is the best free physics puzzle game? #
Cut the Rope for classic puzzles, Poly Bridge 3 for building, and Brain It On! if you like problems with several solutions. All three are free and rated 4+.
Are there physics puzzle games with no ads and no in-app purchases? #
World of Goo 2 ($9.99) and Bridge Constructor ($0.99) are one-time purchases. Apple Arcade titles also can’t carry ads or purchases, so a subscription buys the same peace.
Which physics puzzle games work offline? #
Cut the Rope says so on its store page, and most single-player puzzle games do, since the levels ship inside the app. Test any game in airplane mode before a flight, as described in slingshot games that work offline.
What’s a good physics puzzle game for a young child? #
Bridge Constructor Playground and the Thinkrolls series are built for younger players, and Cut the Rope is rated 4+ with short levels. Our full list is in physics puzzle games for kids.
Do physics puzzle games use real physics? #
They use simplified rigid-body physics with numbers picked for feel, not accuracy. Gravity, weight and bounce are all tuned by the designer, which is why two games can feel completely different while running near-identical maths.
