ATS (Against the spread) – One of the most popular types of sports betting is betting “against the point spread” (also known as ATS). The point spread is a total number the bookmakers set with the intention of evening the playing field between two teams. Setting a spread gives a reason for bettors to bet on either side of the game. When betting against the spread there is a “favorite” and an “underdog.” The  favorite to win the game is considered the better team and listed with a minus (-) sign. The underdog is the team not expected to win the game and is listed with a plus (+) sign. To win your bet by betting on the – point favorite, your team needs to win the game by more than the point spread. To win your bet betting on the + money underdog, your team needs to either lose by LESS points than the spread, or to win the game outright. If the score ends equal to the spread the wager is considered a “push.” If your wager is considered a push, it will be voided and your wager will be returned.

Bookie, Bookmaker, House, Sportsbook, etc. – A bookie, bookmaker, house, or sportsbook is the person or entity who facilitates gambling, most commonly on sports or a casino. A bookie, bookmaker, house, or sportsbook is someone who sets the odds, accepts the bets, and pays out winnings.

Buying Points – When betting against the spread certain bookmakers allow you to “buy points.” Buying points lets you alter the point spread in your favor of the team you want to wager on. If offered, the sportsbook charges you in exchange for moving the line in your favor. Usually, it costs an extra 10 cents for each half point you buy. If the spread is -3 for -110, buying points allows you to buy the spread to -2.5 for -120. If the spread is +3 for -110, buying points allows you to buy the spread to +3.5 for -120. Usually, after getting to the -170 range, buying points will cost more than an extra 10 cents and will continue to go up the further you buy or sell the line. 

Chalk – The favorite and often the team that the most money is on. 

Circled game – A game where the betting action is limited. Usually these are games that have some level of uncertainty about them still such as injuries, bad weather, starting lineups, etc. When a game is “circled” you will normally see a “C” next to them.

Normally the status will change once the variables which were up in the air are made clear.
