Osmos is a puzzle video game developed by Hemisphere Games for different systems as Microsoft Windows, Mac OS X, Linux, iPad, iPhone and iPod Touch. It is available on-line for $10 USD or £6.99 GBP. The game was made available on Steam on August 17, 2009.[1] The aim of the game is to propel yourself, a single-celled organism (Mote), into other smaller motes to absorb them. Colliding with a mote larger than yourself will result in being absorbed yourself, resulting in a game over. Changing course is done by expelling mass. Due to conservation of momentum, this results in the player's mote moving away from the expelled mass, but also in his/her own mote shrinking.

There are three different "zones" of levels in Osmos: In the sentient levels, the goal is to prevail over active motes of various types that hunt and absorb other motes, including the player. Hunting them typically involves absorbing as many inactive motes as possible before chasing down the active ones with the extra mass one has gained.

In the ambient levels, the player's mote typically floats in a large area surrounded by inactive motes, and must become the largest or simply very large. Variations on this theme involve, for instance, starting the game as a very small mote surrounded by lots of larger, fast moving motes, or the presence of "antimatter" motes which shrink normal motes during collision no matter which one was originally bigger, or starting the game stuck in a huge, densely packed area with a large number of other motes without much space to move about and having to nudge other motes out of the way by ejecting mass at them.

In the force levels, special motes (Attractors) influence other motes with a force similar to gravitation. The player has to take into account orbital physics when planning movement in order to save mass when changing course. In these levels, the game optionally assists the player with a course trajectory tool that plots the mote's course, up to a short time in the future. Force levels are complicated in various ways, including levels with mutually repelling attractors, attractors bouncing randomly around an area full of motes, several "strata" of bodies in retrograde rotation about an attractor, and attractors orbiting other attractors.
