How to play
How to play Planet Clicker
Planet Clicker is a simple idle loop: tap for Mass, spend Mass to grow faster, repeat. There is no limit and no losing state — every session leaves your planet bigger than it started.
- 1
Tap the planet
Click or tap the planet in the center of the board to collect Mass. Each tap adds your current click power, shown just below the planet.
- 2
Buy generators
Spend Mass on generators — Dust Collectors, Comets, Space Stations, and more — that keep producing Mass automatically, even between taps.
- 3
Buy upgrades
Upgrades permanently boost either your click power or your total production. Each one only needs to be bought once.
- 4
Watch your planet evolve
As your lifetime Mass climbs, your planet grows through nine visual stages — from a loose cloud of Space Dust up to a full Galaxy.
Tips to grow faster
- Buy your first two or three generators before spending on click upgrades — passive income compounds while you read this sentence.
- Re-check the shop after every purchase; a generator you could not afford a moment ago is often affordable now.
- Click upgrades matter most early, before your generators are producing much on their own.
- Watch for the "Buy Max" option once you have surplus Mass — it is the fastest way to convert a stockpile into more generators.
- Production upgrades (the catalysts) multiply everything at once, so buy one the moment you can afford it.
- There is no penalty for switching tabs between Generators and Upgrades — compare prices before committing your Mass.
FAQ
Planet Clicker, answered
Authoritative answers about Planet Clicker — the free idle clicker game you can play online in your browser.
What is Planet Clicker?
Planet Clicker is a free online idle/incremental game. You tap a planet to collect Mass, spend that Mass on generators and upgrades, and watch your planet evolve through nine visual stages — from a scattering of Space Dust up to a full Galaxy. It runs entirely in your browser with no download.
How do I play Planet Clicker?
Click or tap the planet to earn Mass equal to your click power. Spend Mass in the Generators tab on units that keep producing Mass automatically, and in the Upgrades tab on one-time boosts to your click power or total production. Your lifetime Mass determines your planet's current evolution stage.
Is Planet Clicker free to play online?
Yes. Planet Clicker is completely free and runs entirely in your browser. There is nothing to buy, download, or install, and there are no ads interrupting play.
Do I need to download or install anything?
No. Planet Clicker is a 100% browser-based game built with HTML, CSS, and JavaScript. It loads in Chrome, Edge, Firefox, Safari, and other modern browsers on desktop and mobile without a plugin or installer.
What should I buy first in Planet Clicker?
Buy the cheapest generator you can afford, repeatedly. Dust Collectors and Comets are inexpensive and their output adds up quickly once you own several. Click upgrades are worth grabbing early too, since they make every tap worth more while your generators are still small.
How does Mass production work?
Each generator produces a fixed amount of Mass per second per unit owned; owning ten Comets produces ten times what one Comet produces. Production (catalyst) upgrades multiply your total output from every generator at once, so buying one is always a big jump in growth.
Do generator prices go up?
Yes. Each generator's price rises by about 15% every time you buy one more, which is standard for idle games. This keeps cheaper generators worth revisiting instead of only chasing the newest, most expensive one.
How do I reach the later planet stages?
Reaching Star, Black Hole, or Galaxy is entirely about lifetime Mass, which only ever goes up. Keep buying the best-value generators and upgrades, and prioritize production (catalyst) upgrades the moment you can afford them — they compound every generator you own.
Does Planet Clicker save my progress?
Yes. Your Mass, generators, upgrades, and best lifetime Mass are saved locally in your own browser as you play. Nothing is sent to a server, and there is no account or login required.
Does Planet Clicker have offline progress?
No — Mass only accumulates while the game tab is open. This is a deliberate choice: it keeps every player's progress verifiably earned rather than a number that ran up in the background.
Can I play Planet Clicker on mobile?
Yes. Planet Clicker is touch-first: tap the planet to collect Mass, and use the Generators and Upgrades tabs below it to shop. The layout adapts to phones, tablets, and desktops.
