Planet Merge

Every launch changes the shape of the board in Planet Merge. A small planet can drift into the perfect position for a merge—or bounce into a crowded corner and create a new problem. The goal is to combine matching planets until they evolve into larger celestial bodies, with the Sun waiting at the end of the progression. Space is limited, so every shot needs a little planning before you let it go.

How To Play Planet Merge

The game starts with the smallest planets and gradually introduces larger ones through merging. When two planets of the same size touch, they combine into the next stage of the cosmic chain. Instead of dropping planets wherever there is room, pay attention to how they move after landing. Gravity and collisions can change their position, making a well-placed shot much more valuable than a rushed one.

Build Toward The Sun

There are ten planetary stages to create before reaching the final goal. Early merges leave plenty of space to work with, but later rounds become more crowded as larger planets take up more room inside the circular arena.

Chain reactions can help clear space when several planets combine one after another. Setting up those opportunities often works better than chasing a single quick merge.

Don't Let The Board Overflow

The edge of the arena is just as important as the center. A large planet pushed too close to the boundary can end the run if it pops outside the circle. Try to spread planets across the play area instead of stacking everything in one section. Keeping the board balanced gives you more room to create future merges.

Tips For Better Merges

• Watch where a planet is likely to bounce before releasing it.

• Create small merges early to leave more space later.

• Avoid piling large planets against the edge.

• Look for chain reactions instead of forcing one merge at a time.

• Keep the center open so future launches have more landing options.
