Planet Merge Game

Planet Merge is a relaxing cosmic puzzle game that combines physics-based gravity with addictive merge gameplay. Set in a celestial bubble, players drop asteroids and minor planets from the top of the screen to combine matching bodies. Merging two identical celestial objects triggers a reaction that upgrades them into a larger, more complex planet, starting from small asteroids all the way up to a massive star.

Success in Planet Merge requires strategic thinking and spatial planning rather than quick reflexes. As you drop more planets, the container fills up, and you must manage the limited space carefully. Every object has physical properties, causing them to bounce, roll, and settle on one another in unpredictable ways. If the planets stack up too high and cross the top threshold, your game will end. It runs seamlessly in your web browser with no download or setup required.

Controls

• Mouse Move / Drag: Move your mouse cursor (or drag your finger on mobile) left and right to aim where you want to drop the celestial object.
• Left Click / Tap: Click the left mouse button (or tap the screen) to release the planet and let it drop.

Tips

• Keep small planets on top: Try to keep your largest planets at the bottom of the container. If a tiny asteroid gets trapped beneath a massive planet, it becomes almost impossible to merge, wasting valuable space.
• Use gravity and momentum: Planets will roll along curves. You can drop a planet slightly to the side of a match and let it roll into place, using gravity to merge objects that are not directly aligned.
• Do not rush your drops: There is no timer in the game. Take your time to analyze where a dropped planet will land and how it might bounce or shift the planets already in the container.
