Planet Merge — Play Free Online

Planet Merge Description

Planet Merge is a free browser merge puzzle set in space. You launch planets into a circular play area, and when two of the same size touch, they merge into one bigger planet. There are ten sizes in total, from small moons up to gas giants, and the goal of every run is to keep merging until you build the Sun. The controls are one button. Move the mouse to aim, press and hold to set your angle, and release to launch the next planet. On mobile, drag and release the same way. There is nothing else to learn, so the first round is playable in seconds. The hard part is the physics. Every planet you launch gets pulled by gravity once it is inside the play area, so it can bounce, roll, and drift into neighbors you were not aiming at. You are predicting paths as much as aiming. Space runs out faster than it looks. The play area is a circle, and every planet you drop takes up room. If anything gets pushed over the rim, the run ends immediately. A good placement can set off a chain reaction that merges several pairs at once, clears space, and piles up points. A careless one can clog the middle and leave you nowhere to put the next planet. There are no levels and no timer. Your score comes from the size of the planets you create and how long you keep the pile from overflowing. You can squeeze in a run during a break and stop whenever you need to. Planet Merge has nothing to do with football; it is a space merge puzzle about matching planets and knowing when not to drop. It runs free in any modern browser on this site with no download and no account.
