The reverse is also the same the gambler takes the favorite and it is 13 - 4 = 9 </Li> <P> Spreads are frequently, though not always, specified in half - point fractions to eliminate the possibility of a tie, known as a push . In the event of a push, the game is considered no action, and no money is won or lost . However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event . Sports books are generally permitted to state "ties win" or "ties lose" to avoid the necessity of refunding every bet . </P> <P> Betting on sporting events has long been the most popular form of spread betting . Whilst most bets the casino offers to players have a built in house edge, betting on the spread offers an opportunity for the astute gambler . When a casino accepts a spread bet, it gives the player the odds of 10 to 11, or - 110 . That means that for every 11 dollars the player wagers, the player will win 10, slightly lower than an even money bet . If team A is playing team B, the casino is not concerned with who wins the game; they are only concerned with taking an equal amount of money of both sides . For example, if one player takes team A and the other takes team B and each wager $110 to win $100, it doesn't matter what team wins; the casino makes money . They take $100 of the $110 from the losing bet and pay the winner, keeping the extra $10 for themselves . This is the house edge . The goal of the casino is to set a line that encourages an equal amount of action on both sides, thereby guaranteeing a profit . This also explains how money can be made by the astute gambler . If casinos set lines to encourage an equal amount of money on both sides, it sets them based on the public perception of the team, not necessarily the real strength of the teams . Many things can affect public perception, which moves the line away from what the real line should be . This gap between the Vegas line, the real line, and differences between other sports books betting lines and spreads is where value can be found . </P>
