About This Game

2.0 UPDATE: Cards, Slots, Rebirth, and more!

You start as a tiny pool of slime... weak, slow, and outnumbered. Hover over smaller slimes to eat them, absorb their essence, and grow stronger with every drop.

Spend it on a skill tree of over 200 upgrades: chain lightning, darts, orbiting slimes, crits and more.

Hit milestones to draw Cards, then collect and equip them to build your slime your way.

Earn spins and try your luck on the Slot Machine.

Send allied slimes into the Ooze Mine to keep growing while you're away.

Be reborn to earn souls and buy permanent boons, and grow faster every time.

Learn every slime type, catch the gold slimes before they escape, and face the Primordial Slime

If you get lost, don't worry, Garry the Slime Snake is here to walk you through it!
