Thanks for the heads-up about this, guys. Here's how I got my 10k miles (yet to be credited) and walked away £8 richer [8D] :
Play roulette and bet on any of the thirds. Double up on every bet you lose, so that when your number comes up, you'll always be a little bit better off (WARNING: If you're very unlucky, or don;t have the funds to back yourself up, you can lose all your money. This tactic works for me and might not work for you, so please don't invoice me if you end up having to remortgage your house

). Once you've boosted your coffers by about £10, keep placing £4 bets on both red AND black, and stick 20p on 0.
This way, you'll soon rack up £100 worth of stakes, and you'll only lose a couple of quid. (Some of you might not want to bet the 20p on 0, but I recommend it because it pays 35 to 1 (£7 from 20p stake), so you'd lose £1.20 if the 0 comes up, as opposed to £8 if it comes up and you've not bet on it.
Like I said à it works for me but isn't fool-proof.
