About Planet Merge
Planet Merge is a free puzzle game you play in your browser, where you launch planets and merge matching pairs until the Sun appears. Two identical planets combine into a larger one, and there are 10 sizes to work through. You can play Planet Merge online with just a mouse, and there is nothing to download.
Cosmic gravity sets the game apart from a plain drop-and-stack puzzle. Nearby bodies influence each other's movement and position, so where a planet lands and what it bounces into matters as much as the planet itself. If any planet pops outside the circular play area, your run ends immediately.

Tips to get better at Planet Merge
- Do not drop planets at random. Think a few moves ahead and aim for merges that create new merges.
- Predict the bounce. Gravity and nearby planets shift a launched planet, so allow for drift before you fire.
- Avoid stacking high in one spot. Large merged planets can push others over the boundary, so spread the load across the circle.
- Check the edge as the circle fills up, and use merges to thin out crowded areas before they become a problem.
- Go for chain reactions when you can. They free up room and move you toward the Sun faster.
