Planet Merge

Planet Merge is a space puzzle game about combining matching planets to create bigger ones. Planets move around the play area with physics, so every placement can change what happens next.

When two matching planets touch, they merge into a larger planet. Keep making matches to unlock bigger worlds, from small moons to huge planets. Your goal is to build the biggest planets you can while keeping enough free space for the next ones.

Merge Planets and Build Bigger Worlds

Each new planet adds another piece to the puzzle. Matching planets can start useful chain reactions, but bad placements can quickly fill the available space.

Large planets take up more room, so the game gets harder as your solar system grows. You need to think ahead and leave space where future matches can happen.

Keep the Space Under Control

The main challenge is stopping the planets from piling up too high. A crowded area makes it harder to bring matching planets together. If the planets overflow the available space, the run ends.

• Merge identical planets into larger ones.


• Discover bigger planets as you progress.


• Create chain reactions for more merges.


• Plan around bouncing and moving planets.


• Keep enough empty space for future matches.


• Try to reach the largest planet possible.

A Simple Space Merge Puzzle

Planet Merge starts simple, but the board becomes harder to manage as the planets grow. A good merge can clear useful space, while one bad placement can leave smaller planets trapped between larger ones.

So the challenge is not just making the next match. It is setting up the board so you can keep merging and build an even bigger solar system.
