About This Game
Out there somewhere, but nobody has found it — a planet merge puzzle themed around "Planet Nine" 🚀 Launch planets like billiard balls and merge matching ones, growing from tiny Mercury toward the ninth planet 🌟 3-5 minutes per run, played with a mouse. Scores go to global leaderboards 🪐
Detailed Description
🪐 Merge planets and unravel the mystery of the universe!
It's out there somewhere, yet no one has ever found it——the "ninth planet". Collide cute planets together, merge them, and uncover the secret yourself.
🌟 Aim, shoot, merge
Launch a planet like a billiard ball and send it crashing into another of the same kind — they'll merge into one! Grow from tiny Mercury toward the larger planets, one merge at a time. 3-5 minutes per run, played with just a mouse. Perfect for a quick break, and easy to come back to again and again.
🚀 Features
A cast of original, adorable planet characters
A unique physics-based merge system — think billiards, but in space
Merging planets can send others flying your way — deflect them before they cross the line!
A cozy, relaxing space world to get lost in
Playable in 17 languages, including English and Japanese
🏆 Regional and global leaderboards
Your high scores go to both your country's leaderboard and the global one, ranked across daily, monthly, and all-time boards. How far can you climb? And what will you find when you finally reach the ninth planet...?
