Astro Merge

About Astro Merge

Astro Merge turns the night sky into a puzzle board. Bright little planets drift down one at a time, and you drop each one where it belongs. When two matching planets touch, they fuse into a single larger world — so every careful placement brings you one step closer to a giant glowing sphere.

The rhythm is the hook: each drop takes a second, but deciding where it lands can take much longer. Gravity tumbles every planet after release, the pile grows relentlessly, and keeping it low while chasing bigger merges is the whole delicious tension. No timer pushes you along — just you, the stars, and the quiet satisfaction of small worlds combining into something bigger, in short breaks or long sessions alike.

How to Play Astro Merge

Move your mouse or finger to aim the falling planet, then click or tap to drop it. Gravity settles it among the pile — line up matching planets so they touch and merge into the next size up.

Score by merging upward through the sizes while keeping the pile below the top line. If the stack crosses the line, the run ends, so spend safe drops widening the base before chasing big merges.

Tips & Strategies

Keep big planets low and centered. Heavy planets roll. A big world parked on a slope will nudge everything sideways, so settle large merges at the bottom center where they cannot topple the pile.
Sort small planets to the sides. Feed tiny planets down the edges toward their matches instead of dropping them mid-pile. Center drops bury future merges under clutter.
Wait for the wobble to stop. Dropping mid-tumble is how careful plans become avalanches. Let the pile fully settle before releasing the next planet.
Chase one size at a time. Pick the next merge size and aim every drop at it. Scattered almost-matches across three sizes look busy but score nothing.
