Planet Merge
Launch matching planets, use gravity to build larger worlds, and protect the bubble boundary as you work toward the Sun in Planet Merge.
Planet Merge starts with a simple shot: aim one planet, release it, and look for a matching body. The board gets harder when gravity sends the new arrival rolling into another planet or pushes a carefully placed cluster toward the edge. Build the chain toward the Sun while keeping the circular play area under control.
About Planet Merge
Planet Merge is a space-themed puzzle game where matching planets combine into larger celestial bodies. The game features 10 planets, and each successful pair moves you closer to forming the Sun. The growing collection must stay inside a circular bubble, so merges and space management matter together.
Every launch can change the board. Planets may bounce, roll, or collide with nearby bodies, and different placement angles create different follow-up positions. The cute cosmic theme keeps the presentation light, but the key decision is serious: make a merge now or preserve room for a better pair later.
How to Play Planet Merge
Click and drag to aim, then release to launch the planet. When two identical planets touch, they fuse into the next larger planet. The surrounding bodies do not stay perfectly still after impact, so check the new layout before choosing the next launch.
A planned placement is more useful than a random drop. Keep matching bodies close enough to reach, arrange the cluster so a new large planet has room, and avoid building an isolated planet against the boundary. Larger bodies take more room, and a planet that escapes the allowed area ends the run.
Tips for Planet Merge
- Set up the next pair - Think one launch beyond the obvious match so the new planet does not block your next move.
- Protect the outer edge - Crowded planets and strong collisions can push a body outside the play area.
- Expect movement after every impact - Recheck the cluster because a bounce can open or close a merge opportunity.
- Use merges to create room - A safe combination can be more valuable than a risky chain when the bubble is full.
Game Controls
- Click and drag - Set the launch direction.
- Release - Send the planet into the bubble.
FAQ
How many planets can you merge in Planet Merge?
Planet Merge features 10 different planets that combine into larger bodies on the path toward the Sun.
What happens when a planet leaves the bubble?
The run ends immediately if a planet pops outside the circular play area.
Why does gravity matter in Planet Merge?
Gravity affects how planets travel and collide after launch, so the final position may differ from the place you first aimed at.
Planet Merge rewards a clean board and deliberate placement. Keep the cluster inside the bubble, use gravity to your advantage, and play Planet Merge online to chase the next larger world.
