About Astro Merge
Astro Merge is a puzzle game about guiding falling planets into a growing stack. Matching planets combine, creating larger results while adding to your score. The simple drop mechanic gives each move a useful purpose, and the rising pressure makes every placement matter.
The blocky space theme keeps the board easy to read as you work toward a bigger stack and a better high score. Combos are especially satisfying because one successful merge can change the shape of the stack and create room for another planet.
How to Play Astro Merge
Use your mouse or finger to aim the falling planet at the part of the stack where it can fit best.
Click or tap to release the planet. Once matching planets meet, they merge and contribute to your score.
Build combinations while managing the available space, since the pressure increases as the stack grows.
Tips & Tricks
- 1Place planets beside matching ones whenever possible so future drops have a clear merging target.
- 2Use the wider gaps in your stack for planets that do not have an immediate match.
- 3Plan each drop around the shape of the current stack instead of aiming only for the highest open spot.
