In soccer, you can bet on a traditional spread, such as -1, -1.5 etc.  Soccer also offers an Asian handicap, which is a spread that list anything ending in .25 or .75.  When you make this bet, it will split your stake in half, with half the stake going to the half point below the mark you set, and half the stake going to the half point above the mark you picked. For example, if you bet Liverpool -1.75, half your stake will go to the odds offered at -1.5, and half the stake will go to the odds for -2.  Should Liverpool win this game by exactly 2, half of your stake at the -1.5 odds will payout, and half the stake on -2 will result in a push.  

You can also choose to bet an in-game spread, meaning you can bet what the spread will be for the remainder of the game.  If Liverpool is currently winning 1-0, you can make a bet on Liverpool to be -1 for the remainder of the game, so they would need to win by 3 for this wager to be a win. Your betslip will show what the current score was when you made the spread wager.
