About this game
Astro Merge is a stacking puzzle game where planets fall from the top of the screen and you decide where each one lands. When two matching planets touch, they merge into a bigger one, and chaining merges together is how you climb the leaderboard. Every drop is a small gamble on balance and timing.
As the stack grows, the pressure ramps up. The longer you hesitate, the more likely your tower becomes unstable, so the game rewards quick, confident decisions. Chasing your own high score from run to run is where most of the fun comes from.
Tagged as an .io-style title, it suits short sessions and repeated attempts. Open it in your browser and you can start stacking right away.
How to play
Move your mouse to aim where the planet will fall. Click to drop it. Merge matching planets to grow your stack and raise your score. On touch screens, slide your finger to aim and tap to drop.
