Planet Merge is a charming, engaging cosmic puzzle game. In this game, you will guide the little meteorite Sputnik on his ultimate journey. Evolving through each stage to become a bright, warm Sun.
Your goal is to drop and merge two identical planets together. With each successful merge, they combine into a larger planet. So, you can unlock the next step of cosmic evolution. However, space inside the cosmic bubble is limited. As planets grow bigger, they take up more room. If your planets stack up past the red boundary line, the game ends immediately. Plan every drop with care!
BASIC INSTRUCTIONS
At the start, the game gives you random small celestial bodies. Players need to aim the shots so the incoming planet lands right against another of the same type. You will click, hold, and drag the mouse to set your shot power and aim line. Then you will release the planet into the cluster on the right. The moment two identical bodies touch, they merge into a larger one.
Ten-stage cosmic evolution system
Along the journey to help Sputnik become the sun, you will discover ten different celestial bodies. Each one has its own distinct color, size, and fun facial expression. Ranging from tiny, curious meteorites to gentle blue planets and finally the glorious sun.
Increasing difficulty
There is no time limit, giving you all the time you need to think through every shot. However, the pressure builds as available space inside the bubble shrinks. Keep challenging yourself to beat your personal high scores
Shoot your ball
Click and hold on the planet, and drag to adjust power and aim direction. Then release to shoot it into the circular bubble containing the other planets.
Tips to shoot in Planet Merge
- Keep your largest planets settled at the bottom and place smaller ones on top.
- Aim small planets slightly off-center so they can roll down the curves of bigger ones.
- Wait patiently to let chain reactions play out as planets roll and settle together.
- Group planets of similar evolutionary tiers close to each other for easy combo merges.
