Space Blobs is a free arcade game developed by Simplicial Software LLC for Android. The game takes place in the year 4,039,213,741, where intergalactic radioactive space blobs have invaded the Earth after the sun exploded. The player is the last line of defense and must clear all the blobs from the planet's surface before it's too late.

The game-play is simple yet engaging. The player must rotate the planet to position the orbital laser over the blobs to destroy them. However, the laser color must match the color of the blob, or else the blob will grow even faster. The game has two modes: Normal mode with 40 patterned levels followed by an infinite number of randomly generated levels, and Survival mode for those who seek a challenge.

Space Blobs also offers leader-boards and a variety of achievements for players who sign in. However, high scores can be tracked even without signing in. Overall, Space Blobs is a fun and challenging arcade game that is worth trying out.
