What it does.

Real soft-body slimes.

Every slime is a ring of mass points held together by springs, with a heavy hub in the middle. They wobble on landing, squish under weight, and slide around each other like real jelly.

Merge to climb.

Two slimes of the same tier that touch will merge into the next tier up. Only the smaller five drop in, so the big ones only exist if you build them.

Native iOS.

Built in Swift, SwiftUI, and SpriteKit. Runs offline. Works on every iPhone running iOS 17 or later.

Take your time.

No timer, no stamina meter, no cosmetic shop. Drop one slime in a minute or fill a whole bowl in an hour. Whatever fits.

How to play

Three steps.

  1. Drop.

    Tap along the top of the bowl to drop a slime where you want it.

  2. Merge.

    Two same-tier slimes that touch merge into one slime, one tier bigger.

  3. Survive.

    Keep the stack below the danger line. A settled slime above it ends the game.
