What is Planet Merge?
Planet Merge is a browser-based merge puzzle game developed by JMD and launched in 2026. The game tasks players with launching orbital spheres into a central gravitational field to fuse identical bodies into larger worlds. Unlike standard vertical drop games, gravitational forces draw nearby space objects toward each other across the cosmic arena. The entire experience runs directly in modern web browsers without requiring any downloads or installations.
Key features
- Orbital physics: Gravitational forces pull neighboring celestial objects toward one another inside the arena.
- Merge progression: Combining two matching spheres transforms them into the next planetary tier, advancing from small moons toward massive gas giants.
- Trajectory aiming: Holding down your pointer displays an aiming guide before releasing the object into orbit.
- Cross-device support: Runs smoothly via mouse controls on desktop computers and touch gestures on mobile devices.
- Readable visuals: Distinct planetary colors and scales help you identify matching pairs across the field.
How to play
- Check the incoming planet positioned at your launcher and identify open targets in the arena.
- Click and hold the mouse button or press the touchscreen to aim your shot.
- Release your hold to launch the planetary sphere toward the gravitational center.
- Collide identical celestial bodies to merge them into larger worlds and clear valuable space.
- Prevent the playing area from overflowing by continuously combining matching worlds into giant gas planets.

Orbital merge mechanics
Every shot introduces a new celestial body into the orbital zone. When two identical planets collide, they immediately merge into a single sphere of the subsequent size class. Because gravitational pull pulls surrounding bodies together, careful placement can trigger secondary merges when shifting objects settle into adjacent positions. Allowing unmatched worlds to accumulate will eventually congest the field and bring the session to an end.
Tips and strategy
- Group identical bodies near each other: Keeping matching planets close together ensures that orbital gravity can quickly snap them into a merge.
- Leave pathways for upcoming shots: Avoid walling off small moons behind larger planets, which prevents direct access for future merges.
- Watch the gravitational pull: Because spheres slide toward one another, take a moment after each launch to let the orbital field stabilize before firing again.
- Focus on creating larger gas giants: Combining intermediate worlds reduces crowded clusters and opens up critical room on the playing field.
- Keep the launcher zone unobstructed: Overfilling the central area limits your aiming angles and increases the chance of ending your run early.
