BTW, I abhor how they've changed up the odds system. Part of why I haven't gotten involved in online betting until now and why I will rarely use a sports book. Say the odds are 4-1. Great! That's easy math. But, "Hey, this team is +650" and the math is like WTF???
PS: I'm a math idiot.
Most books will allow you to change from the American system to fractions if that is easier. (although if you aren't good at math, you might not be good at fractions)
It is really easy to figure out though. Every bet is based off $100.
Plus bets are the easiest to figure out.
+650 means, that if you bet $100, you win $650.
Minus bets work the same, but in reverse.
-650 means that in order to
WIN $100, you have to wager $650.
