Keep your money in your pocket mate.

It will be somekind of 'martingale' system where you bet red or black and simply keep doubling your stake when you lose.

So you bet £1 on red. If it's black, you stake £2 on red next time. Then £4. You get the idea. Eventually, Red will win (so the theory goes) at which point, you recover all previous losses and make the £1 you originally wanted to make.

In theory it works. But it only takes a bad run and you need a bank account like Bill Gates to play. After 10 losses, you're staking £1024 to make your £1 profit.

And even if you have the money and balls to do it, you'd find the casinos set a maximum limit.

Can I have my £50 now mate ?
