MergeCosmos

MergeCosmos - Play Online

Merge puzzle meets space theme. Drop celestial bodies. Match them. Watch them grow. MergeCosmos is all about stacking stars without hitting the red line.

How to Play MergeCosmos

Your goal is simple: Drop bodies. Merge matching ones. Score points. Don't cross the red warning line at the top or it's game over.

Drop and Match

Click or tap anywhere on the board. Body drops straight down. Two identical bodies touch? Instant merge into a bigger one. Plan your landing spot. Bad placement = wasted space. Physics do the rest—bodies roll, settle, stack.

Space Management

Board fills fast. Pack bodies tight. Leave room for merges. Watch the red line. Cross it? Dead. Use the Hammer to remove one body when things get messy. No hammers left? Watch an ad. Get one free.

Strategy Tips

Drop bodies near their twins. Create merge chains for bigger scores. Don't panic—use Pause (top-left) to think. Out of moves? Watch a rewarded ad to revive and keep playing. Aim for high scores and climb the Leaderboard.
