So What I'm getting from this is that in the below mentioned scenario is that San Francisco is supposed to win by 7 points. am I right?
TEAM MONEY LINES SPREAD TOTAL
SEATTLE +240 40
SAN FRANCISCO -290 -6½
When wagering on SAN FRANCISCO you must win by at least 7 points to win the bet. When wagering on SEATTLE you cannot lose by more than 6 points to win the bet. On the other hand if the line was a solid -6 and SAN FRANCISCO wins by exactly 6 points then the bet is a "push", and stake or money is returned to your account.
Wagering on the total points combined on the game: To win on the "over", the total score for each team will be added together and it must exceed 40 points. When betting the "under", the total score for each team is added together and cannot exceed 39 points to win the wager, if the total score add up to exactly 40 points, the bet is called a "push" and the money is credited to your account.
Money Line Wagering
When wagering on the money line, you must win the game on the field in order to win your bet. Wagering on SAN FRANCISCO $-290, the point spread does not matter. You must risk $290 to win $100. Wagering on SEATTLE $+240, you stake $100 to win $240.
