If you're searching for an addictive idle clicker game that lets you unleash cosmic destruction, Planet Buster is a must-try. Released in October 2025, this space-themed casual game combines simple mechanics with satisfying progression, allowing players to demolish planets and asteroids using automated missiles.

What is Planet Buster?

Planet Buster is an addictive idle-clicker game set in space, where players destroy orbiting planets and asteroids using automated missiles. Each planet features multiple layered shells that must be chipped away to reach the core, triggering explosive destruction and earning currency for upgrades. With rhythmic progression, gravity mechanics, and boss battles, it blends automation with engaging visuals for endless replayability in the idle genre.

How to Play Planet Buster

Getting started with Planet Buster is straightforward, making it accessible for beginners while offering depth for veterans. The game runs directly in your browser on desktop, tablet, or mobile devices, requiring no downloads.

Destroying Planets and Asteroids

The gameplay loop revolves around obliterating celestial objects. Each level presents a rotating planet or asteroid with layered defenses. Missiles chip away at these layers automatically, but manual clicks speed things up. Once you breach all layers and hit the core, the planet explodes in a visually rewarding blast, earning you currency (coins) based on the damage dealt.

As you progress, you'll encounter tougher planets with thicker shells. Currency earned from destructions is used to purchase upgrades, enhancing your missile capabilities. The game is idle so missiles are still fired and you still accumulate points even without direct manipulation. Completing a set of planets leads to boss encounters - massive, resilient worlds that test your upgrades. Defeating a boss unlocks new galaxies with unique visuals and challenges, keeping the experience fresh.
