circloO is a colorful physics platformer in a growing circle. This app version contains all levels from circloO and circloO 2, plus brand-new bonus levels! There's also a level editor and already over 10,000 levels created by players like you! You're a small ball rolling around in a round level. Collect circles to grow the level circle. As it grows, everything stays in the level, so you'll have to avoid and use obstacles in everchanging ways. For example, a platform that was first very useful to gain height, may prove to be a challenging obstacle after the level has grown! You can only move left and right, so you'll want to use features of the level carefully to jump and gain height. You'll discover all sorts of physics features, such as changing gravity, a sea of tiny blocks, strange contraptions and even planets with a gravity field. In challenging parts, you'll find yourself fully immersed, pressing the screen as hard as you can trying to get closer to finally collecting that next circle. But don't worry: you'll never have to start over a level, so you can always try again really quickly! And I can guarantee you'll feel amazing once you finally manage it! circloO Complete features: - Lots of cool physics features: ropes, pulleys, changing gravity and much more! I've included quite a few mechanics for you to discover. - Over 75 fun, growing, ever more challenging levels! Can you complete the six almost-but-not-quite-impossible Hard Mode levels? - There's also a level editor and an ever increasing number of player created levels! - All levels from circloO 2 and the original circloO, plus 28 brand-new levels! - Unique physics puzzles in each level. - Great music and sound effects by Stijn Cappetijn. - Minimalist and colorful graphics. - The game will take most players three to five hours to complete. Level times are saved, so you can try to beat your own highscores and speedrun levels after that! Plus there are thousands of player-created levels to continue playing forever! - Relaxing yet challenging physics puzzle platforming fun! I'm very happy that circloO 2 on the web won the first Crazy Games developer contest out of 200 contestants! It was also third in the Kongregate contest of November 2018. You may remember it from CoolMath Games as well. Reviews: "It’s an excellent game that has a very playful and chilled out approach to the gameplay, whilst also featuring some wonderfully intricate level design. A very impressive puzzle platformer you’ll really want to roll with. Highly recommended." - Free Game Planet "The difficulty scales upwards nicely and you're constantly rewarded for learning new skills as these always come up in future levels." - Jayisgames The game contains occasional ads after a level, which can be removed with a one-time in-app purchase, which supports development as well. Have fun and I'm happy to hear what you think!

Verdict
circloO and Physics Box Game both sit at 4.8 stars, but that hides the real split: 89% of circloO's written reviews are positive against 50% of Physics Box Game's. circloO also leads on ratings volume (2.4K vs 1) and iOS requirement (10 vs 13.0). Physics Box Game's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. circloO sells 1 one-off in-app purchase. Physics Box Game asks for nothing beyond the download.
Physics Box Game holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: circloO has 2.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of circloO's written reviews are positive against 50% of Physics Box Game's, so the app with the better star average is not the one people write more warmly about.
circloO ships an update every 2 months, Physics Box Game every 3 weeks. The most recent releases landed on September 26, 2026 and September 13, 2026 respectively.
