Forget complicated controls and prepare for a tiny cosmic adventure. In Planet Merge, every drop brings Sputnik one step closer to the Sun as adorable planets collide, combine, and grow. What starts as a calm merge puzzle quickly becomes a test of timing and positioning when gravity sends planets rolling and bouncing into unexpected places. With limited bubble space and bigger celestial bodies constantly taking up room, every move counts.
Ready to enjoy the charming planetary chaos!
How the Merging System Works
The main mechanic is straightforward: combine 2 identical planets to create 1 larger celestial body. However, bigger planets take up more room, gradually compressing the available space and making future drops harder to manage. After each launch, gravity takes over as planets can roll, bounce, and shift surrounding objects. These unexpected collisions may create useful chain reactions, but they can also push planets toward the dangerous bubble boundary. The key is to think about both the immediate merge and where the surrounding planets will move afterward.

Controls
- Use the mouse to aim by dragging the incoming planet into your preferred position
- Release the mouse button to launch it onto the board
Survival Rules for Beginners
- Preview Your Drops: Don't rush—always calculate where the planet will bounce before releasing it
- Prevent Trapped Space: Avoid trapping small planets beneath heavy, large ones, which creates unfillable gaps at the bottom
- Utilize Edge Placements: Use wall-bounces and precise side drops to push crowded center piles back toward the middle
- Monitor the Boundary: Watch the upper bubble line closely when space becomes tight; crossing it ends your session immediately
