Some games demand your full attention. Planet Clicker takes the opposite approach, and somehow, that makes it harder to quit. Click a planet, earn energy, unlock Mars and Venus, and build an automated solar empire in your browser. No downloads. No accounts. No cost.


About the Game

What Is Planet Clicker?

Planet Clicker belongs to the incremental game genre, sometimes called idle games or clicker games. The core loop is simple: click to earn resources, spend resources on upgrades, let those upgrades do the clicking for you, then reinvest and repeat.

What separates it from the dozens of other clicker games out there is the setting. You are not baking cookies or running a paperclip factory. You are colonizing planets. Earth gives way to Mars, Mars gives way to Venus, and each new world brings a fresh set of upgrades and a noticeable jump in energy output.

The game was originally created on Scratch by developer Coltroc. It runs entirely in-browser with no installation, no launcher, nothing to manage.



The Planets

Three Worlds to Conquer

Each planet plays differently, demands a different approach, and rewards a different kind of patience.


Earth

Your starting point. Slow pace, cheap upgrades, fully manual at first. Spend early and often. The compounding effect starts sooner than most players expect.


Mars

Where things open up. Resource generation accelerates, automation becomes viable, and the upgrade tree expands. Most players love this stage most.


Venus

The endgame. Energy numbers get large, upgrades get expensive, and patience becomes the main skill. Reach here and you have built something real.



Features

Core Features Worth Knowing


Incremental Energy System

Everything runs on energy. Clicks generate it, upgrades multiply it, automation sustains it. The system scales smoothly across all three planets without hitting a wall.


Upgrade Shop

Click multipliers, auto-generators, and efficiency boosters each play a different role. Learning the right purchase order is most of the game.


Idle and AFK Progression

Leave the tab open and the game keeps running. Come back an hour later to a stockpile of energy you did not have to work for.


No Account Required

No sign-up, no login, no email verification. Open the site, the game loads, you play. Progress does not save between sessions so keep the tab open.



Strategy Guide

What Actually Works

  • 1
    Do not save up for one big upgrade
    Three mid-tier upgrades will outperform one premium one, especially early on. Spend frequently and consistently. The compounding effect rewards speed over patience at this stage.
  • 2
    Click hard in the first few minutes
    Before automation kicks in, manual clicking is your only income source. Go fast, stack energy quickly, and get your first round of upgrades bought as soon as possible.
  • 3
    Prioritize Mars early
    Mars is not just the next planet. It is a multiplier on everything you have built. Once you are close to the unlock threshold, redirect all spending toward getting there.
  • 4
    Let idle time work for you
    Leave the tab open while doing something else. The energy accumulates passively, and returning to a full stockpile makes your next upgrade wave much more powerful.
  • 5
    Balance clicking power and automation
    In the mid-game it is tempting to go all-in on auto-generators. But click multipliers still matter for active sessions. A good ratio of both keeps you earning efficiently either way.
