About Planet Clicker

Planet Clicker is an incremental clicker game with a space colonization twist. Instead of clicking cookies or gold coins, you click a planet to produce energy units — a resource you funnel into progressively powerful upgrades. The game starts small on Earth with basic options like campfires and farms, but the scope expands dramatically once you save enough energy to unlock Mars and eventually Venus.

What keeps players coming back is the satisfaction of watching numbers climb and entirely new upgrade tiers appear. Developed by Coltroc and originally released on the Scratch platform in March 2020, Planet Clicker runs as a lightweight HTML5 game in any modern browser. There are no accounts to create and no apps to install — just open the page and start clicking. If you enjoyidle tapping gameswith a clear sense of progression, Planet Clicker offers that same loop at a planetary scale that feels genuinely rewarding to push through.

How to Play Planet Clicker

Basic Controls

Planet Clicker uses one-button controls. On desktop, left-click directly on the planet displayed on screen to generate energy. On mobile devices, tap the planet instead. To navigate between planets once you have unlocked them, use the arrow buttons at the bottom of the screen. The upgrade shop sits alongside the planet view, where you spend accumulated energy on production boosts.

Main Objective

Your goal is to produce as much energy as possible and use it to colonize three planets in the solar system: Earth, Mars, and Venus. Each planet has its own set of upgrades, and unlocking a new planet requires hitting a specific energy threshold. There is no fail state or game-over screen — Planet Clicker is an open-ended incremental game where progress itself is the reward.

Energy Production and Upgrades

Every click on Earth earns you 1 energy point to start. Once you reach 20 energy, the shop opens up and you can upgrade your click power so each tap produces more. After a few hundred energy, automatic sources become available — the first is the campfire, which generates 1 energy per second on its own. From there, the upgrade tree branches into farms, power plants, and more advanced production buildings.

Once you accumulate enough energy from Earth, you can purchase Mars through an interplanetary energy transfer. Mars introduces upgrades like solar oil, coal, nuclear power, and alien technology. Venus is the final frontier, costing 1 trillion energy units to unlock, and features high-tier options such as iron processing, lava energy, and the powerful “Future Technology” upgrade sitting at the bottom of its list.

Switching Between Planets

After unlocking a new planet, switch back and forth freely using the arrow buttons at the bottom of the screen. Each planet retains its own upgrade tree, so managing where you invest energy becomes a key strategic decision. You do not lose progress on one planet by visiting another.

Idle Progression

What separates Planet Clicker from pure active-clicker games is that automated upgrades continue generating energy as long as the game tab remains open in your browser. You can invest in passive production, leave the game running in a background tab, and return to a stockpile of energy ready for your next round of purchases.

Planet Clicker Tips and Strategies

1. Upgrade click power before anything else

In the first minute, manual clicking is your only energy source. Spend your first 20 energy upgrading click power rather than saving for something expensive. Each click-power upgrade compounds immediately, letting you reach the campfire threshold much faster than raw clicking alone.

2. Stack cheap upgrades instead of saving for big ones

It is tempting to hoard energy for the next tier, but buying multiple affordable upgrades produces more total energy per second than waiting. For example, stacking several campfire upgrades early on outpaces skipping them to rush an animal farm. Incremental spending keeps your production climbing steadily.

3. Transition away from clicking as soon as possible

Clicking matters in the opening minutes, but it quickly becomes insignificant compared to automated production. Once your passive generators are running, shift all spending toward boosting their output. After a few upgrades, your auto-sources will produce in one second what would take dozens of manual clicks.

4. Set a savings target before unlocking Mars

It is easy to keep dumping energy into Earth upgrades endlessly, but unlocking Mars gives you access to significantly more powerful production options. Once your Earth production is self-sustaining, stop spending and let energy accumulate toward the Mars threshold. The new upgrades on Mars accelerate your overall output far beyond what Earth alone can achieve.

5. Revisit cheaper planets after unlocking new ones

Mars and Venus have flashier upgrades, but lower-tier upgrades on Earth may still offer a better cost-to-output ratio. Switch between planets regularly and compare prices — sometimes a cheap Earth upgrade gives you more energy per second per unit spent than an expensive Mars option.

6. Leave the tab open for passive gains

Since automated generators only run while the browser tab is active, keep Planet Clicker open in the background during other tasks. This is especially useful when saving for Venus, which costs 1 trillion energy units — passive accumulation over time makes that number reachable without hours of active clicking.

7. Aim for Future Technology as your endgame target

The Future Technology upgrade on Venus is the most expensive and most powerful option in the entire game. Treat it as your long-term goal to give your playthrough direction. Every upgrade decision along the way should factor in whether it helps you reach Venus faster or produces enough output to fund Future Technology once you arrive.
