About this game

Drop planets. Merge the pairs. Build your way from Pluto to the Sun.

Kosmomo is a space merge puzzle with one twist that changes everything: gravity pulls toward the centre of the arena, not down. Every planet you drop curves in, rolls around the core, and settles into orbit — so the board you are building is round, alive, and never quite where you left it.

If you like suika-style merge puzzles, the watermelon drop games where two of a kind combine into something bigger, this is that idea rebuilt in orbit.

HOW TO PLAY

Aim along the rim. Drop a planet. When two of the same planet touch, they merge into the next one up. Pluto becomes the Moon, the Moon becomes Mercury, and eleven merges later you are holding the Sun.

One round teaches you everything. Stopping is the hard part.

WHY IT FEELS DIFFERENT

Most merge games drop straight down into a jar. Kosmomo drops into a gravity well. Planets swing past each other, nudge the pile, and settle in ways you did not plan, so a board that looked finished can open up a merge you never saw. Physics does half the work. The other half is knowing when to wait.

Short rounds. One thumb. Perfect for a queue, a commute, or the ten minutes before sleep.

Merge your first Sun and you will understand why people keep going back for one more drop.
Drop planets, merge the pairs, reach the Sun. A circular-gravity space puzzle.
