Build your own tiny solar system in Planet Merge! Combine matching planets, create massive worlds, and aim for the Sun without letting your system overflow the bubble.
Planet Merge – Merge Your Way to the Sun
Planet Merge is a space-themed merge puzzle game where tiny planets collide, merge, and evolve into larger celestial bodies. Every drop can alter the entire layout within the bubble. Match identical planets, utilize collision physics, and keep your system within the boundaries. Can you build an entire solar system with just a few precise drops?
Gameplay
In Planet Merge, when two identical planets touch, they merge into a larger planet. However, unmatched celestial bodies remain on the board and can be pushed around by subsequent collisions. You receive a new planet each turn; drag your mouse to choose a position and release to drop it. When two planets of the same type touch, they merge into a larger body. Keep merging new planets to advance to higher levels.
Evolve to the Sun
The ultimate goal in Planet Merge is to build an evolutionary chain—starting from small planets, progressing to massive celestial bodies, and finally reaching the Sun. As you advance, the planets take up more space, making it increasingly important to keep the layout organized after every merge.
Collision Physics
The fun of Planet Merge lies in how the planets react after dropping. They can bounce, roll, and push surrounding bodies. A single drop doesn't just affect the new planet's position; it can trigger a chain reaction and unexpectedly create opportunities for "chain merges."
Respect the Bubble's Boundaries
Space in Planet Merge is limited. As the planets grow larger, available space shrinks, and the pressure mounts. If a planet drifts out of the safe zone following a collision, the game may end. Therefore, do not focus solely on creating the largest planet; keeping the cluster of planets balanced and compact is just as important as scoring points.
