Play Cool Ball Online

Cool Ball is one of those weird little Game Boy gems where you're just a bouncy ball trying to survive increasingly chaotic levels. At first it seems simple—you hop between platforms, grab some points, find the key to exit—but then you hit a sticky platform and suddenly you're flailing to break free before falling into lava.

The backgrounds change as you progress (starting with a cosmic theme before jumping through time), which keeps the visuals surprisingly fresh for such a straightforward game. My favorite part? The random tools you collect—like water drops to put out fires or hammers to smash walls—that make you rethink how to approach earlier levels if you replay them. Some of the angled platforms will absolutely wreck you until you get the timing down.

It's the kind of game where you'll fail a level ten times, then suddenly nail it and feel like a genius.
