it's a big green thing with balls on it.

the idea is to use the q (this long stick thing), to pot your coloured balls.

but if you pot the black one, it's game over

you pot the balls in to what they call pockets, little hole type things that are situated at various points around the table

that's my explanation for the day... I hope it made at least some sense. not theb est when someone asks me to explain something
