Newbie: Check my pointspread arb calculation

[gotme]

Team 1 -3.5(-115)
Team 2 +3.5(-105)

If I were getting a 10% bonus on both accounts.
If I were to place an even bet of say $300 on each team:

Team 1 wins: Win 255, lose 300, bonus 60 = 315 = $15 profit
Team 2 wins: Win 285, lose 300, bonus 60 = 330 = $30 profit

Am I getting this correct? Am I able to lose this bet at all?

Thanks.

you won't be able to withdraw the bonus at the account you win at until you place more bets.

there is a way to make money on sports bonuses doing something similar to what you are thinking, but it's slightly more complicated and long term.

What if the bonus had a 3x playthrough?

Bonus per account is $30 and I've wagered 10x times that per account.

Does that work?

Better check your terms & conditions because virtually all sportsbook bonus wager requirements are calculated relative to the deposit+bonus.

Thus a 10% bonus with 3X WR for a $30 bonus would have a wager requirement of ($300 deposit + $30 bonus) = $330 x3 = $990 per bonus or $1780 total for 2 $30 bonuses.
