Planet Merge

Planet Merge brings the satisfying mechanics of a merge puzzle into space. Launch planets into a circular play area, combine matching worlds, and keep evolving them into larger celestial bodies while trying to reach the Sun. The game uses physics-based movement, so every launch can change the position of several planets.

How to Play Planet Merge

The rule is simple: send a planet into the bubble and try to make it collide with another planet of the same type. Two matching planets merge into one larger body, opening the way for the next combination.

As the planets grow, available space becomes more valuable. A successful run depends on creating merges without allowing the bubble to become too crowded.

Aim Before You Drop

Planet Merge uses a straightforward drag-and-release system. Move the mouse to choose your angle, then release to launch the current planet.

Don't focus only on the immediate target. Think about where the planet will move after the collision and whether the resulting position will help or hurt your next move.

Let Gravity Do Some of the Work

Planets can bounce, roll, and move after making contact with other celestial bodies. Gravity adds an element of unpredictability, meaning one carefully positioned launch can sometimes lead to several merges.

Learning how the planets react to collisions is one of the most useful skills for improving your score.

Keep the Board Manageable

Small planets are easy to place at the beginning, but larger bodies quickly consume space. Avoid creating unnecessary piles that leave little room for the next drop.

When possible, use a merge to clear space while also preparing another combination. Good positioning becomes increasingly important as your solar system grows.

Tips for a Higher Score

• Plan the landing: Consider where the planet will finish after bouncing or colliding.
• Create space: Don't let large planets dominate the board too early.
• Look for chain merges: One collision may position another pair for an easy combination.
• Use gravity: Experiment with different launch angles to understand how planets move.
• Think ahead: The best drop isn't always the one that creates the fastest merge. Choose positions that leave useful options for your next turns.

Start Merging

Planet Merge is easy to understand but becomes more strategic as your celestial collection grows. The combination of matching planets, physics, and limited space keeps every run active and gives you plenty of opportunities to improve your score.
