There are countless planets, stars, solar systems and other formations in space that fill the endless expanses of space. The game Merge Planets invites you to create only some of them. The list is at the bottom of the screen. The principle of the birth of planets and stars is the merger of two identical ones. Drop space objects from above and push them together. The result will appear if two identical elements collide. This will result in a new planet or larger star. If even one cosmic body falls outside the limited area, the Merge Planets game will end.
