Planet Pi is a simple strategy clicker game developed by Supernova Republic for Android devices. This game combines elements of idle games and strategy, where you have to add buildings to get more resources and start capturing the world. The main objective of the game is to unlock all 5 major planets and conquer the galaxy.

The game is set on a planet surrounded by hostile tribes, and the player must train soldiers and send them to neighboring planetoids to capture them. As the player captures more colonies, their army grows bigger. It is essential to balance resources to wage war or grow the population to prevent riots.

All game processes occur in real-time, and while the player is resting, the extraction of resources continues, ships fly toward their goal, and the player's army grows. The game also allows players to sign in to Google Play Games to save their progress and access achievements.
