Planet Buster - Idle Space Clicker Game

Planet Buster is an idle casual space-themed clicker game where your primary objective is to systematically destroy planets across multiple galaxies using an arsenal of automated missiles and strategic upgrades. Launched on October 6, 2025, by Azgames, this addictive destruction simulator transforms planetary annihilation into visual art through its smooth interface and rhythmic pacing.

Core Gameplay Loop

The game begins with a spinning asteroid awaiting destruction. Your base automatically launches missiles that continuously bombard the planet’s surface, gradually reducing its size layer by layer until the core explodes in a brilliant eruption. Each planet consists of distinct layers—crust, mantle, and core—and you must blast through all of them to claim victory. You can tap or click the “Press to bomb” button to activate automatic attacks, and each missile impact deals damage while earning currency for upgrades.
