Planet Clicker

How to play

Click the planet to harvest energy. Every click adds a unit to your total, plus a small bonus that grows with your grid, so early clicks matter and later clicks still help. When you have enough energy, build your first generator from the panel on the right.

Each generator harvests energy on its own, measured as energy per second. A Solar Panel trickles power, a Wind Turbine spins in the storms, a Power Plant burns steady fuel. The more you own of a generator, the more it costs, so prices climb as you scale up. New generators appear as you get close to affording them.

That is the whole loop. Click to get moving, build generators so you earn without clicking, then plough that energy into bigger generators. The number only goes up, and there is no losing, just how fast your grid grows.

How to earn energy fast

Early on, build the cheapest generator you can afford and keep clicking between builds. Solar Panels and Wind Turbines pay for themselves quickly and get your energy per second off zero.

Once you have a steady flow, stop hoarding and spend. A rough rule is to build whatever gives you the most energy per second for each unit spent, which is usually the newest generator you can just afford. Do not sit on a huge reserve, put it to work in generators that harvest more.

Because the grid keeps running while the tab is open, and banks a capped amount while you are away, the fastest players check in, build a round of generators, and leave it running. Come back later to a far bigger number and a panel full of generators you can suddenly afford.

The generators

There are eight generators, each stronger and pricier than the last. The Solar Panel and Wind Turbine are your starters, cheap and steady. The Power Plant and Solar Satellite are the mid game, where your energy per second really starts to climb. The Moon Base and Fusion Reactor turn harvesting into an industry.

The Dyson Ring and Star Forge are the late game, each harvesting tens of thousands of units a second once you own a stack of them. You will not afford them for a while, and that is the point. Every generator you build pulls the next one into reach, so the panel always has a goal a little beyond your current reserve.

Build in breadth, not just depth. A spread of many generator types usually out harvests pouring everything into one, because each new type opens a bigger energy-per-second jump than the tenth copy of an old one.

Does it save, and is it unblocked

Your star system saves automatically in your browser, so you can close the tab and come back to the same energy, generators, and rate. Nothing is uploaded and there is no account, the save lives on your device.

The game runs entirely in the browser with no downloads and no plugins, so it works on a school or office network the same as anywhere else. There is nothing to install and nothing to unblock, just open the page and start harvesting. If you clear your browser data the save resets, so keep that in mind before wiping it.
