joking aside, its pretty easy, roulette wheel, ball, roulette table.
Place your bet there are a few options
on a colour (red or black)
on a specific number
on a row of numbers
on a set of numbers
(covers it nicely) Roulette – Wikipedia, the free encyclopedia
ball gets spun, if it lands on a colour or a number that you have chosen you win, depending on what you have chosen depends on the odds payout with a single number choice being the highest.
