Particle is a free Android game developed by hirotakaster. It falls under the simulation category and allows you to create particle patterns on your device. The game supports a maximum of 10 finger points multi-touch at a time. Single tap resets the particle positions, and double-tap opens the settings. The surface view allows the use of alpha afterimage effect, and the GL view can use up to 10,000 particles. Particles gather and leave at the center of your fingers.

Overall, Particle is a fun and interactive game that lets you create unique particle patterns. The game is easy to use and provides a relaxing experience. However, there are no additional features or levels, so the game may become repetitive after a while.
