I was looking through all the prop bets and you can bet on odd/even total of any game. But the weird thing is that the line is -161 for an odd final score. +120 for an even final score on every single game. Is there some reason behind this? Most games tally ends at odd? I'd think it be -110 for both. And the games that have an over/under of 10 are still +120 for even total. Wouldn't the book be betting against itself if the line was predicted correctly? Just found it interesting.
