Mergeon

Drop planets, merge with real physics, and climb the orbit toward the Sun. Undo once, tune sound, beat your best score.

Mergeon is a relaxing physics puzzle inspired by merge games: drop planets into the well, let them collide and merge into bigger worlds, and score every time you combine.

HOW TO PLAY • Tap to drop the current planet where you want it to land. • Identical values merge into a larger body (with special rules for the smallest tier). • Watch the red danger line — keep the stack from staying above it too long or it’s game over. • Reset starts a fresh round; your best score is tracked on device.

FEATURES • Smooth Matter.js physics and canvas rendering. • Orbit strip shows your progression from the outer solar system toward the Sun. • Satisfying merge sound with a mute control (preference saved locally). • One undo per round until you use it; refills when you reset.
