About Planet Merge
The grid of floating planets finally snaps into order: three Jupiters collide, and the screen shimmers as they fuse into a single Saturn. That blink of visual payoff — a larger planet replacing the three that fed it — is the reward Planet Merge keeps offering. Every drag-and-drop decision aims for that moment, when mismatched colours lock into place and a chain reaction ripples across the board.
Merge planets in this cosmic sorting puzzle! Just drag and drop to align matching celestial bodies, watching them combine into bigger, cooler planets. It's simple to pick up but requires strategic thinking to line everything up perfectly. The satisfying chain reactions and the urge to organize the galaxy make it seriously addictive. Click and drag to sort your way through space.
How to Play Planet Merge
- Use your mouse to drag a planet from one tile to an adjacent empty or matching tile.
- Left-click to drop the planet onto the target tile.
- Line up three or more planets of the same colour to merge them into a larger celestial body.
- Planets can only move to an adjacent tile — no skipping across the grid.
- Keep merging to clear space and prevent the board from filling up.
Game Features
- Drag-and-drop controls let you shift planets one tile at a time with a single mouse click.
- Merging three identical planets triggers a chain reaction that can clear large sections of the grid at once.
- Each successful merge produces a visually distinct larger planet, adding a sense of progression.
- Endless mode means the board keeps generating new planets until no moves remain.
Tips & Strategies
- Plan your path before you drag: a single move can open a gap that lets you reach a planet you need for a triple match.
- Watch for planets close to the edge — merging them clears space along the border and gives you more room to reorganise.
- When the board gets crowded, prioritise matches that remove planets from the centre first; they block the most movement.
Frequently Asked Questions
What happens when three planets of the same colour merge?
They disappear from the grid and a single larger planet (like a Saturn or Neptune) appears in their place, scoring a chain reaction.
Can I move a planet diagonally?
No. Planets can only be dragged to an adjacent tile — up, down, left, or right — not diagonally.
Is there a time limit or do I have unlimited moves?
There is no timer. The game continues as long as you can keep making matches; the round only ends when the board fills up with no merges left.
