Enter the ambient world of Osmos: elegant, physics-based gameplay, dreamlike visuals, and a minimalist, electronic soundtrack.

Your objective is to grow by absorbing other motes. Propel yourself by ejecting matter behind you. But be wise: ejecting matter also shrinks you. Relax - good things come to those who wait.

Key features:

  • Independent Games Festival finalist in three categories: Seumas McNally Grand Prize, Excellence in Design and Technical Excellence
  • Progress from serenely ambient levels into varied and more challenging worlds. (47 levels, plus bonus content)
  • Confront attractors, repulsors and intelligent motes with similar abilities and goals as you
  • Selected as one of the 2009 PAX 10
  • Procedural content: play random versions of any level
  • Sublime electronic soundtrack by Loscil, Gas/High Skies, Julien Neto, Biosphere, and more
  • Dynamic time-warping: slow down the flow of time to outmaneuver agile opponents; speed it up to raise the challenge

Osmos reviews and comments

Perfect Game to Switch off for in between with a very atmospheric Soundtrack. Each Set of Levels revolves around a specific Challenge built on the previous one. Within a Set, the Levels become heavier and heavier, so it can get very demanding in places. The Perimeter goes for the Price in Order Conclusion: 11/10 would buy;)

Astrophysics simulator, with an exquisite and relaxing soundtrack. By far, the best gaming experience for iOS since it all came out of the iPhone 4S. I have not found anything to your height an.

Incredibly enjoyable pastime! Atmospheric music and easy control make this little game my favorite. Gy with variations in the boards, and sometimes you have to think a bit before moving on. Should the game be longer!

Great game concept with nice atmosphere. Previously very enjoyable to play, and now with multiplayer completely non-disposable ('unputdownable'). And what's great: every game starts symmetrically, so both players have exactly equal chances. Recommended !!

A solid game where much of the detail has been made. However, there are not many hours of gameplay, so the game becomes boring and monotonous. It is the $ 18.00 worth, and it is also entertaining to fly through the universe in Aecade fashion, but then the development stops and the game becomes boring. However, it deserves 4 stars anyway!

At first glance, the game may not make an impression, but in many places it's a gravity simulation, it takes into account momentum conservation, and so on, at the end of the day you can learn a lot about physics, but you need a bit of patience and the game can be frustrating If you want to teach your kids from the age of 7 to physics, you should definitely buy the game!

I have been waiting for this since I saw and played the iPad version. What a great and unique game that gives you a Zen-like experience when you play it. Especially with headphones on playing otherwise the experience is a lot less. That is because of the in game music that after a while puts a kind of trance on you so that you are completely calmed down. Blindly purchase I would say !!!

It may look simple, but it is not. Rarely had a game here in the store that leaves me so often back home for several iPhone generations. It creates an aesthetic balance between design and game feel. Balls that are left to let shrink but also give you a boost. What is greater than oneself absorbs oneself, which is smaller than oneself, is absorbed. Such a simple concept but so effectively implemented. One of my all-time favorites in the store!
