Slime Lab is an io-style game where you control Slime in a petri dish. The entire dish is constantly visible on the screen and you watch what are your opponents doing and where mysterious scientists add nutrients and anti-nutrients.

Your task is not to get eaten by the big Slimes and be the first to get the nutrients from the pipette maneuver between anti-nutrients and escape from the big Slimes. As you grow and getting bigger you can eat other Slimes or you can lure them into traps lure them into anti-nutrients or use other strategies to remain the only Super Slime in the petri dish.

As you progress through the game at each new level the number of your opponents their size at the start will keep increasing and increasing you will have to eat them all and earn more and more rewards!
