Planet Clicker
Conquer the Solar System One Click at a Time
About This Game
Planet Clicker is one of the most successful clicker games ever made on Scratch, with over 6.6 million plays and counting. Created by Coltroc, this space-themed incremental game puts you in charge of generating energy across the solar system, starting from Earth and expanding outward to colonize Mars, Venus, and beyond.
The game follows the classic Cookie Clicker formula but wraps it in a compelling space exploration narrative. Each planet you unlock has its own unique set of upgrades, visual style, and progression curve. Earth serves as your starting base where you learn the mechanics, Mars introduces more expensive but powerful multipliers, and Venus pushes you into the late-game exponential growth phase.
What makes Planet Clicker stand out from other Scratch clicker games is its polish and depth. The planet transitions feel like genuine progression milestones rather than just number increases. The background visuals change, the upgrade names become more ambitious, and the scale of your operation grows from a single click to an interplanetary energy empire. Coltroc also built in idle mechanics, so the game continues generating energy even while you are away.
With its massive player count and consistently positive reception, Planet Clicker has earned its place as one of the definitive Scratch incremental games alongside Cookie Clicker and Fun Clicker.
How to Play
Click Planet
Click the planet to generate energy — each click produces energy based on your current click power
Buy Upgrades
Purchase upgrades from the menu to increase energy per click and energy per second
Unlock Planets
Accumulate enough energy to unlock Mars, Venus, and other planets in the solar system
Idle Income
Auto-generation upgrades earn energy passively even when you are not clicking
Strategy Guide
The key to fast progression in Planet Clicker is understanding the upgrade efficiency curve. Early on, focus all your energy on the cheapest available upgrades — they provide the best return on investment. Resist the temptation to save for expensive upgrades when cheaper ones are still available.
Once you have a solid base income from Earth, the transition to Mars is the biggest hurdle. You need a significant energy stockpile to unlock it, so this is where idle income becomes critical. Buy all available auto-generation upgrades before going AFK, and let the game run in a background tab.
On Mars, prioritize the multiplier upgrades over flat bonuses. A 2x multiplier applied to your existing income is almost always better than a fixed +100 energy per second at this stage. The same principle applies when you reach Venus — multiplicative scaling is king in the late game.
General tip: never stop buying the cheapest available upgrade. In incremental games like this, sitting on a pile of unspent currency is always suboptimal. Spend early, spend often.

Why We Love It
With 6.6 million plays, Planet Clicker has clearly resonated with the Scratch community, and for good reason. It takes the proven Cookie Clicker formula and adds a genuine sense of progression through its planet unlock system. Each new world feels like a real achievement rather than just a number going up. Coltroc nailed the balance between active clicking and idle income, making it equally satisfying whether you are actively playing or checking in after a break. It is the kind of game that keeps pulling you back for just one more upgrade.
Pro Tips
- 💡Always buy the cheapest available upgrade first for maximum efficiency
- 💡Prioritize multiplier upgrades over flat bonuses in the mid-to-late game
- 💡Let the game run in a background tab to accumulate idle energy
- 💡Each planet has unique upgrades — explore them all
- 💡The transition from Earth to Mars is the hardest part — be patient
Frequently Asked Questions
How many planets are in Planet Clicker?▼
Planet Clicker features multiple planets in our solar system including Earth (your starting planet), Mars, and Venus. Each planet has its own unique visual theme, upgrade tree, and progression curve. You unlock new planets by accumulating enough energy on your current planet.
What is the best upgrade strategy in Planet Clicker?▼
The most efficient strategy is to always buy the cheapest available upgrade first, as it provides the best cost-to-benefit ratio. In the early game, focus on flat energy bonuses. Once you reach Mars and beyond, prioritize multiplier upgrades over flat bonuses — a 2x multiplier on a large income base is far more valuable than a small fixed increase.
Does Planet Clicker have idle/offline progress?▼
Yes, Planet Clicker has auto-generation upgrades that produce energy passively. Once you purchase these upgrades, the game continues earning energy even when you are not actively clicking. However, you need to keep the game tab open — it does not track progress when the browser is closed.
How long does it take to beat Planet Clicker?▼
There is no definitive end to Planet Clicker as it is an incremental game designed for ongoing play. Unlocking all planets can take several hours of active play, or a day or two with mostly idle income. The fun is in the journey of optimization rather than reaching a specific endpoint.
Who created Planet Clicker?▼
Planet Clicker was created by Coltroc on Scratch. It is one of the most popular Scratch games ever made, with over 6.6 million plays. Coltroc is also known for creating other popular Scratch projects including Candy Clicker.
Is Planet Clicker related to Cookie Clicker?▼
Planet Clicker is inspired by Cookie Clicker's incremental gameplay formula but is an entirely separate game with its own space exploration theme. While Cookie Clicker focuses on baking cookies, Planet Clicker is about generating energy and colonizing planets. Both games share the satisfying click-upgrade-grow loop that defines the clicker genre.
