About Planet Merge

Planet Merge is a casual physics puzzle game released in 2026, built around a simple drop-and-merge idea. The goal is to combine matching celestial bodies to create larger planets and eventually reach the Sun. What makes this Planet Merge game different from a basic merge puzzle is the gravity system. After each launch, planets can bounce, roll, and collide with nearby objects, so a drop can lead to several merges at once. The game has 10 celestial bodies to discover, while the limited bubble keeps the pressure on as the planets become larger.

How to Play

Aim the next planet: On desktop, move and drag the mouse to choose where the planet should land.
Launch: Release the mouse button to drop it into the bubble.
Play on mobile: Drag your finger to aim and release to launch, making the mobile game easy to control without extra buttons.
Merge matching planets: When two identical celestial bodies touch, they combine into a larger one.
Watch the gravity: A planet may move again after bouncing or hitting another body, so the first collision is not always the end of the move.
Stay inside the bubble: If a planet escapes the circular play area, the current run ends.

Good Points

The controls are quick to understand, so most of the attention stays on positioning and timing.
Gravity gives the gameplay more variety than a standard drop-and-merge puzzle.
A well-placed planet can start a chain reaction and clear useful space.
Larger planets increase the score, but they also make the board harder to manage.
The 10-stage progression gives each run a clear target, with the Sun as the final goal.
The small planet characters and simple animations add some personality without getting in the way of the puzzle.
It works well for short sessions, but chasing a better score gives a reason to start another round.

Tips or Tricks

Keep smaller matching planets reasonably close so they are easier to combine later.
Do not build a large pile against the edge of the bubble. Bigger planets need more room to move.
Think about the next collision, not only where the planet lands.
Use bouncing and gravity to reach matching planets that are difficult to hit directly.
Leave open space in the middle for larger celestial bodies.
When the board gets crowded, look for a chain merge that can create space instead of making a quick drop.
