This website lets you have a gamble element with 0% risk involved!
After registering with your Address and password. Click the "Free Play".
Once there you can enter a captcha to "Roll!" once per hour and get a random number between 1 and 10,000. The higher the number you get, the bigger is your payout. The highest number pays more than 0.4 BTC! The payout is once a week, on Sundays. But perhaps the best part of all is the referral program where you earn **50%** of all your referrals earnings. I really can't recommend this website enough, I've only been on for a few days and I already am making decent money! Don't miss out, there some serious cash to be made if you get in quick.
