Merge the planets of the solar system 2048!

This game blends the classic sliding-tile formula with astronomy. Instead of powers of two, you pair matching celestial bodies—starting with Mercury—to evolve them into larger planets. Each slide shifts every orb across the board, and when two identical ones collide, they fuse into the next world up, all the way to Neptune. The challenge is managing the grid smartly, as one messy movement can leave you with no open spaces and end the run. What sets this apart is its educational charm: you naturally learn the order of the solar system while exercising your planning skills. The visuals are clean and minimal, putting the focus squarely on the puzzle. Whether you're aiming for a personal best or just enjoying the meditative flow of combining planets, the game offers a unique twist on a well-known genre.
