Plop a planet,
a dreamy space merge
Drop planets into a cosmic bowl — when matching planets touch, they merge into a bigger celestial body. From stardust to a black hole, a dreamy one-handed merge game with no time pressure.
🪐 Planet drop merge
Stardust → Moon → Earth → Sun → Black Hole: an 11-tier merge chain that follows real celestial sizes. Matching planets merge through playful physics.
✦ Draws & a 44-piece collection
Every merge earns Nebula Dust — spend it to draw planet skins. Four rarities from Common to Legendary; duplicates become shards for level-ups.
🎨 Equip skins for score multipliers
Equip collected skins per tier and they appear on the board, adding rarity × level score multipliers. The more you collect, the prettier your board.
🌌 Global ranking
Compete for the best score worldwide with just a nickname. Tap ranking entries to see which planets other players used.
💡 Frequently Asked Questions
Q. Can I play without an internet connection?
Yes. The game is fully playable offline. An internet connection is only needed for the global ranking and for showing ads.
Q. Where is my game data stored?
All progress — collection, levels, Nebula Dust — is stored only on your device. Only the nickname and scores you submit to the global ranking are stored on our server.
Q. Do I have to create a nickname?
No. The nickname is just a ranking display name, and you can skip it and still enjoy the whole game. With a nickname set, new best-score runs are submitted to the ranking automatically.
Q. Are there in-app purchases?
No. Pongdangbyul is completely free with no in-app purchases, and is supported by ads. Nebula Dust, the draw currency, is earned just by playing.
Q. Are rewarded ads mandatory?
No. Rewarded ads (refill plays, free draw) only play when you choose to tap the button — they are entirely optional.
