About Solar Merge: Relaxing 2D Space-Merging Puzzle

Solar Merge is a relaxing 2D space-merging puzzle built around one satisfying loop: launch planets, combine matching ones, and keep building toward the ultimate celestial body — the Sun. Planets are pulled toward the center of the galaxy, so every launch carries real weight as the space around them fills up. One scene shows a central large blue circle packed with a cluster of smaller multicolored spheres, giving a sense of how quickly the galaxy can crowd.

The game is simple to pick up, satisfying to play, and genuinely challenging to master as the stakes rise with every merge.

How to Play Solar Merge

The goal is to merge small planets into progressively larger ones and ultimately create the Sun — the biggest object in the solar system. Aim carefully before each launch, because as more planets fill the galaxy, available space shrinks fast and a single bad placement can spiral into chaos.

• Aim at the spot where you want the next planet to land.
• Release to send it toward the center of the galaxy.
• Two matching planets that touch each other merge into the next larger planet.
• Bigger planets earn more points, so keep chaining merges upward through the solar system.
• Use gravity, collisions, and open space to set up your next merge.
• Avoid letting too many planets build up near the outer danger area.
• Survive as long as possible and beat your high score.

Controls

• Aim: Point toward where you want to launch the next planet
• Release: Send the planet toward the center of the galaxy
