** Apple Design Award winner and iPad Game of the Year! ** Enter the Darwinian world of a galactic mote. To survive, absorb smaller organisms and grow—but beware of larger predators. Osmos features unique physics-based play, stellar graphics, and a hypnotic ambient soundtrack. Absorb or be absorbed! “The ultimate ambient experience” — Gizmodo “Beyond doubt, a work of genius" — GameAndPlayer.net THE CRUX: you must grow by absorbing smaller motes, but to propel yourself you must eject matter behind you, causing you to shrink. From this delicate balance, Osmos leads the player through floating playgrounds, competitive petri dishes, deep solar systems, and more. “Named as iPad Game of the Year for a reason, Osmos is a fantastic game.

You just won’t find another experience quite like it.” — Slide To Play “What iPad Gaming Should Be All About” — Gizmodo “The first proper breakout hit for the iPad.

Verdict
The clearest difference is review sentiment: Osmos at 92% against Solar 2's 64%. Osmos also leads on ratings volume (892 vs 30) and update cadence (every 7 months vs every 21 months). Solar 2's advantage is price ($2.99 vs $3.99) and iOS requirement (11.0 vs 13.4). On ads, in-app purchases, monetization model and chart position there is nothing between them.
