I have done this twice now but have no more cards to use, you can make a one off £5 - £12 on average with no investment and then it's over. Sky Vegas currently offer you £10 No Deposit sign up bonus. Step 1: Sign up to Sky Vegas and enter your card info, do not enter anything in the initial deposit amount box. Step 2: You now have a free £10 from Sky Vegas in your account but you must gamble it to withdraw. Step 3: Click 'Roulette' and Play 'Roulette - Low Stakes. Step 4: Play using 5p bet at a time using the 'Martingale' system if you dont know what this system is, here is a brief overview... E.g 1 - Bet 5p Red - You Win. Great. * Bet 5p Black - You Win. Great. * Bet 5p Red - You Win. Great. * Etc,. (You would now have 30p to withdraw already.) E.g 2 - Bet 5p Red = You Loose - Bet 10p Red = You Loose - Bet 20p Red = You Loose - Bet 40p Red = You Loose - Bet 80p Red = You Win. (You would now have £1.60 to withdraw already.) In essence double your bets until you win then switch colour and start again. This system makes sure your wins covers all previous losses with a small profit. I advise you only play with your 'FREE BETS' do not play with the money you accumulate in your 'BALANCE' as this is Free Cash you can withdraw to your bank and its not worth gambling, i advise you not to use this system with your own cash or make any deposits as eventually, especially when bigger numbers are involved the system will F*** You. Don't try to be a hero. I have now done this twice. The first time i made £10.30, the second £11.85. It took me about 10 minutes each time. Once your free bets are gone regardless of the outcome BAIL. do not get suckered into gambling with your own money. Good Luck.
