Planet Merge Introduction

Planet Merge is a cosmic puzzle game released on 17 August 2026. The game combines planet merging with simple physics and gravity-based interactions, with the goal of helping Sputnik grow toward becoming the Sun. Players drop matching celestial bodies into a limited bubble, where gravity can cause planets to collide and create larger ones. With ten celestial bodies to discover, the gameplay gradually becomes more challenging as larger planets take up more space. The main focus is smart placement, keeping every planet inside the bubble, and building a higher score through successful merges.

Controls & Interactions

• Drag the planet with your mouse to aim.
• Release the mouse button to drop it.
• On mobile, just drag and release with your finger.
• Matching planets merge when they hit each other.
• Gravity can make other planets move and cause extra merges.
• Try to keep everything inside the bubble.

Key Challenges and Obstacles

• The bubble isn’t very big, so space becomes a problem pretty quickly.
• Bigger planets take up much more room.
• Gravity can move a planet somewhere you didn’t expect.
• A bad drop can block an area you need later.
• If a planet leaves the bubble, the run is over.
• Getting a high score means making merges without letting the board get too crowded.

Extra Tricks

• Don’t rush every drop. Check where the planet is likely to end up first.
• Leave some empty space for the bigger planets.
• Try using the sides of the bubble to guide planets toward matching ones.
• Look for chances to make one merge trigger another.
• When the board starts filling up, keeping things under control matters more than making one risky move.
• If you’re chasing a new score, plan a couple of drops ahead instead of only looking at the current merge.
