Asian Handicap: Why Some Lines End in .25 and .75

A handicap gives one side a head start to even out a mismatch. Quarter lines split the stake across two neighbouring handicaps.

The idea

In a handicap market one team is given a goal or points advantage before the match begins. The bet is settled on the result after that adjustment. Asian handicap, which originated in Asia and is described in Wikipedia's article on the subject, removes the draw from football betting by using half and quarter lines.

Whole lines

At -1, the favourite must win by two or more for the bet to win. A win by exactly one returns the stake. That refund is the difference between a whole line and a half line.

Half lines

At -0.5 there can be no refund. The favourite wins the match and the bet wins, or it does not and the bet loses. Half lines are why you often see handicaps of 0.5 in points-based sports as well: they rule out a tie.

Quarter lines

A quarter line divides the stake equally between the two nearest lines.

• -0.25 is half on 0 and half on -0.5. If the match is drawn, the half on 0 is refunded and the half on -0.5 loses: a half loss.
• -0.75 is half on -0.5 and half on -1. If the favourite wins by exactly one, the first half wins and the second is refunded: a half win.

Reading a line quickly

1. Apply the handicap to the final score.
2. For a quarter line, do it twice, once for each neighbouring line, with half the stake on each.
3. Add the two results.
