This is the fun stuff. So this past weekend, one of the casinos ran an awesome deal. Deposits $30-$300 and gamble with it. If you lose 90%, they will refund you your entire deposit. This means if you put in $300, lose $270, they will give you $300 and you can withdraw $330 for a net of $30 risk free.
So I went and did this deal. I got a bit lucky and went to $357 after a couple slot pulls (I had to try to beat $330 or lose $270). Took that money and didn't end up needing the repayment. Either way I would have been happy. In the end, it took about 30 mins researching and playing to earn ~$60 for an hourly rate of $120.
