In the states its all about the points spread. Let's say a NFL game 90% of money wagered is on the line bet eg the favourite is say minus 7.5 points and the outsider is plus 7.5 and the odds are the same eg $1.90. If more money is wagered on one side then the line moves eg if the money is on the face it will move 1 or 2 points to say minus 9.5 and the outsider is now plus 9.5. The win bet for the team is called the money line bet eg $1.50 for the fav and $2.80 for outsider. This bet type is popular here in Australia but not in the USA. Where pointsbet differ from its competitors it also offers a point spread option. You can stake an amount for the team to exceed the line bet eg you can bet the fav to win by more than 7.5 points and be paid out for each additional point the team exceeds the line. However you can lose for each point if they don't. Extremely popular betting option in USA. Huge wins but also huge losses. To further explain check it out on their website but in short you can select to bet $100 on each point variation up to whatever you select eg I could bet $100 for each point exceeding the line and elect say to a maximum variation of 20 points. So if team wins by 30 points I would be paid out 2 but if they lose by 13 points I would lose 2k .
