Super Slime: Black Hole

You begin as a tiny Super Slime: Black Hole blob, and every object around you is a possible snack. A white outline means the item is small enough to swallow. It opens safely in your browser with no install.

About Super Slime: Black Hole

The slime moves with a mouse drag or the W A S D keys. Every item you swallow makes it a bit wider. As you grow, targets you could not touch a moment ago join the menu. Fruit, puzzle pieces, sweets, dice, teddy bears, insects and robots fill the playground, so each round hands you a different shopping list.

Rounds are timed. You need to hit the target level before the clock runs out. Between rounds there are three upgrade branches: Size widens the slime, Time gives extra seconds, Power speeds up your experience gains.

One shot at the boss round

A giant rival shows up at the end of every round, and you get one attempt to take it down. Collected boosters can weaken the boss, so how much you swallowed during the round pays off directly. A win unlocks new upgrades and the loop restarts with a tiny slime again.

Why kids enjoy it

The growth feeling is obvious. The teddy bear you ran from two minutes ago suddenly fits in one gulp. Controls take one hand to learn, and rounds are short enough that starting over never feels heavy.

Is it safe?

The content suits children. Nothing scary appears, and even the boss stays colourful and cartoon-like. Fine for ages 7 and up.
