Planet Clicker 2 is an incremental browser game in which you start as the caretaker of a single world and end up harnessing the combined power of an entire solar system. Everything revolves around one simple action—clicking. Each click produces energy, and energy becomes the currency you invest in bigger reactors, smarter technologies, and ultimately whole new planets. Because the entire loop is visible on-screen at all times, Planet Clicker 2 delivers a hypnotic rhythm that keeps players leaning in for “just one more upgrade.”
From the very first second, Planet Clicker 2 looks familiar to anyone who played the original Planet Clicker, yet it immediately feels grander. The interface has been redesigned with brighter icons, more pronounced progress bars, and sharper planet art, while the core gameplay loop has been expanded with extra celestial bodies, deeper research trees, and more varied energy sources such as nuclear fusion and extraterrestrial tech. That sense of constant escalation—both visually and numerically—is what turns a casual click into a sustained session.
Although Planet Clicker 2 never technically “ends,” it does give you a soft objective: discover every planet, unlock every upgrade tier, and watch your energy per second climb into truly astronomical figures. Because there is no storyline to finish and no time limit, the experience stays friendly to quick five-minute check-ins and to marathon grinding alike. Players who delight in watching numbers skyrocket will feel right at home.
One of the biggest strengths of Planet Clicker 2 is that it lives entirely inside your web browser. No heavy client, no lengthy installation, and no anxiety over system specs—just hit the play button, wait a second for the WebGL canvas to load, and you are harvesting energy from Earth. The game runs smoothly on modern versions of Chrome, Firefox, Edge, Safari, and most Chromium-based alternatives. Even budget laptops or school Chromebooks can usually hit 60 FPS.
Because the save data is stored locally inside your browser’s cache, you can close the tab and return days later to find your empire exactly as you left it. For extra peace of mind, many players export the save string from the settings menu and keep a backup in a text file or cloud note. That way, a routine cookie cleanup won’t wipe weeks of progress.
The entire control scheme for Planet Clicker 2 can be summarized in a single sentence: left-click to generate energy and left-click to purchase upgrades. The developers embraced pure simplicity so the user interface never distracts from the dopamine hit of seeing numbers rise. A scroll wheel or trackpad swipe lets you pan through the expanding list of upgrades on each planet, and that is all you need to master the game.
Right away you will notice two meters in the corner: Energy Per Click (EPC) and Energy Per Second (EPS). The first grows when you buy click-based power-ups; the second grows when you invest in automated generators such as farms, coal plants, solar panels, and nuclear reactors. The secret to fast progress is boosting both at a balanced rate. Over-building EPC feels exciting, but without steady EPS you will stagnate whenever you are not actively clicking.
On Earth, buy the cheapest generator in batches of ten before you splurge on the next tier. Every ten-unit milestone triggers a hidden efficiency bonus, meaning your EPS jumps more than the price tag suggests. Veteran players call this the “10-rule,” and it is easily the fastest way to snowball during the first fifteen minutes.
As soon as Mars unlocks, shift at least 60% of your spending to that red planet. Its mid-tier refineries provide a higher EPS-per-cost ratio than late Earth buildings. Think of Mars as a discount accelerator: investing there compresses the grind so the leap to Venus or the outer planets feels painless.
Once you control four or more planets, manual clicking becomes negligible compared to automated EPS. At that stage focus on global research—particularly reactor fusion and alien technology—because each multiplies every planet’s output simultaneously. You will know you succeeded when the energy counter starts adding scientific notation (e.g., 1.23e+25) faster than you can read it.
Planet Clicker 2 was created by indie developer Coltroc, a solo programmer known for elegant pixel art, clean UI design, and tight incremental loops. Coltroc released the sequel in January 2022 as an HTML5/Unity WebGL build and has patched balance tweaks and performance optimizations through April 2023. The new engine allows higher-resolution textures without sacrificing frame rate, letting players zoom smoothly from planetary overviews to individual upgrade icons.
The sequel’s code also introduced a modular planet system. In practical terms, that means Coltroc can patch in fresh planets, resources, and event-locked technologies without rewriting the core logic. As a result, special holiday events—like meteor showers that double EPS for 48 hours—arrive seamlessly via server-side flags. Players get new content with a simple refresh instead of a full download.
The number one support ticket for Planet Clicker 2 involves missing save files. Ninety-five percent of the time, the browser cleared cookies or site data. To prevent this, regularly export your save code from the in-game settings and paste it someplace
