Combine cosmic bodies and manage space physics in Planet Merge. Drop cute planets inside the bubble boundary, trigger chain reactions, and chase high scores!
What Is Planet Merge?
Planet Merge is a physics-based cosmic puzzle game that transforms popular watermelon-style merging mechanics into an orbiting space challenge. Players aim and launch cute, expressive celestial bodies into a contained orbital field, matching identical planets to form larger worlds while managing tight spatial constraints.
Core Puzzle Mechanics & Space Physics
- Radial Boundary Tension: Unlike standard vertical drop games, planets are contained within a circular bubble field where space shrinks rapidly as celestial bodies grow.
- Gravity Collision Dynamics: Natural gravitational forces cause planets to roll, shift, and collide after impact, opening up surprise chain reaction opportunities.
- Sequential Planet Evolution: Discover ten distinct celestial bodies ranging from tiny moons to massive gas giants as you merge matching pairs.
- Next-Up Queue System: Preview the upcoming planet in the top-left indicator to plan placement angles and long-term board layouts.
How To Play & Control Drops
- Aim Your Launch: Click and drag your mouse around the perimeter to position your trajectory toward the central gravity zone.
- Release to Drop: Release the mouse button to send the current planet drifting into the cosmic pile.
- Match Pairs: Land identical celestial bodies against each other to instantly combine them into the next tier size.
- Protect the Border: Prevent any planet from escaping or overflowing outside the transparent bubble ring to keep your run alive.
Essential High-Score Strategies
- Keep Heavy Planets Central: Place larger worlds near the core so smaller planets can easily bounce off them into secondary matches.
- Account for Rolling Motion: Factor in momentum and orbital curves when launching, as planets rarely stay in the exact spot they first touch.
- Avoid Wall Stacking: Never let smaller bodies get trapped along the outer bubble edge, as they block space needed for bigger merges.
