About Cosmic Merge

Cosmic Merge is a free, relaxing physics puzzle from tlinki. Drop planets into a glass jar. When two identical planets touch, they merge into a bigger one. Keep merging to grow from tiny stardust all the way to a black hole. It works on phones, tablets and computers, needs no sign-up, and can be installed like an app.

How to play

1. Move your finger or mouse (or use ← →) to aim the UFO at the top.
2. Release, click or press Space to drop the planet it's carrying. The Next box shows what comes after.
3. Two identical planets that touch merge into the next size up and earn points.
4. If a planet stays above the red line for too long, the jar overflows and the game ends.

The planets, from smallest to biggest

Stardust → Comet → Moon → Red Planet → Blue Planet → Gas Giant → Ringed Giant → Ice Giant → Sun → Galaxy → Black Hole. Merging two black holes creates a supermassive explosion worth 500 points.

Tips

• Keep your biggest planets in one corner and build smaller ones next to them, like a staircase.
• Look at the Next box before you drop: plan where the next planet will go too.
• Quick chain merges score combo bonuses.
• Your jar is saved automatically, so you can close the page and continue later.
