In an attempt to answer assorted queries and emails about the Mansion free bet promotion all in one place, here goes:
1) For people who aren't used to American style odds and/or point spread bets, it's really pretty easy. Go to Mansion and find the NFL games (I believe they're under "American football" in the links on the top left in the sportsbook. The NFL games for the first week will be listed, with the Pittsburgh/Miami game at the very top.
You will see exactly one possible bet for the Pittsburgh/Miami game, which (as of last night, I'm at work now and can't check it) was the following point spread line:
Pittsburgh -4.5 -110
Miami +4.5 -110
To bet on Pittsburgh to cover the point spread and win the bet, you would check the check box by Pittsburgh, wager $1,100 when asked what to wager, and submit the bet. That's it. The point spread bet is the only bet option available, so there's really no way to screw it up. You don't have to wade through moneyline bets, over/under bets, etc. The bet you see is the one should make, taking Pittsburgh.
2) The first part of the point spread bet (-4.5) determines how many points your team must win by in order for you to win the wager. In this case, Pittsburgh must win by > 4.5 points for you to win. If they lose or win by < 4.5 points, you do not win the wager. If they win by exactly 4.5 points (impossible, in this case), it would be a push and your wager would be returned.
The second part of the point spread bet (-110) determines what you will get paid if you win. For every $110 you wager, you get back $100 if you win. In this example, you wager $1,100 to win $1,000. If you win, your account balance will be $2,100. If you lose, Mansion refunds the $1,100 wager to you within three days, and your account balance will be $1,100.
One thing to note is that while many point spread bets use the -110 number, not all of them do. If you're looking to hedge your bet at Mansion at another book, keep this in mind. Remember, to hedge it perfectly you're looking for another book that's offering Miami +4.5. Let's say you find two books that offer that, with the following lines:
Book A: Miami +4.5 -110
Book B: Miami +4.5 -107
You'd want to go with Book B, as that line is slightly better. Instead of getting $100 back for every $110 you wager, you'd get $100 back for every $107 you wager. So the same $500 wager on Miami made at both books would pay you back slightly more at Book B, since you're getting a better price on each dollar you wager.
When making point spread bets don't just focus on the first number, but also the second, as both are important and determine your ultimate payout. Most point spread bets are set at -110 as a default, but not always.
3) Many reports on 2+2 and elsewhere of people talking with support and confirming that there is no hidden WR with this promotion, whether you win or lose.
They do ask for a copy of ID for anyone who is requesting a cashout, so be aware of that. That's pretty standard for many online casinos and sportsbooks, and you can scan and email it to them, blacking out your actual driver's license #. They're confirming that your official ID lists the same physical address you registered with them, so don't give them bogus info when signing up, or an address that doesn't match what's on your driver's license, passport, etc.
4) Didn't think this needed stating, but if you hedge this bet, don't bet the other side at Mansion, too. You have to hedge bets at different sportsbooks, as many don't like for you to bet both sides of the same game, especially if you received a bonus or are participating in a promotion such as this.
