Planet Merge is a space puzzle game. Join Sputnik on a mission to merge small planets into larger celestial bodies. Each time you drop a planet into the play area, there is a chance of unexpected collisions, so it is very important to choose where to place it.

How to Play Planet Merge Game

Planet Merge is easy to pick up, but it gets progressively more difficult to control the planets as you move along in the game. Drag the planet you want to drop with your mouse, choose a good place, and release the mouse button.

When two identical planets crash, they merge into a larger planet. Each drop, gravity makes the celestial bodies go on rolling, bumping, and changing places. So one drop can actually cause multiple merges in a row. So it can be a little more complicated than it sounds.

Controls

Drag mouse: Move and align the planet's position.

Release the mouse: Drop the planet into the play area.

How to Play Planet Merge

Combining Planets and Making Combos

Planet Merge is more than just finding two identical planets to merge together. Look at the planets on the board and guess where they will go when you add a new one.

And a single drop can cause the planets to collide, creating a new celestial object that leads to even more crashes. These chain reactions help you use your space better and score points faster.

But merging right away isn’t always the best thing to do. Sometimes the best way to avoid a cluttered board is to hold your planets and wait for a good time to jump in.

Planet Merge High Lights

Sweet Planets

The game’s celestial bodies are adorable and have lively expressions. This makes for a light, fun mood even when the board is chaotic.

Merge System

Two planets of the same type can combine to form a larger celestial body. This process unlocks new planetary tiers as you journey toward the Sun.

Gravity

Once released, planets don't just sit still; they are subject to physics. You can roll, slide, or crash into other bodies, so you are guaranteed a different experience every time you play.

Space is limited

The play space is small, and larger planets need more room. Without early planning, you might quickly run out of space to drop your next celestial bodies.

A Variety of Celestial Bodies

Sputnik’s journey takes you through diverse types of planets. Every successful merge brings you a step closer to the end goal of the game.

Challenge: High Score

Experiment with different arrangements to find strategies that activate several merge chains. It’s not just about keeping playing; it’s about beating your own personal best.
