Asian Handicap
The Asian Line is a special type of handicap used for soccer matches. Depending on the strength of each team, a handicap is issued for the game. This enables the odds for each side to be more similar, allowing for more competitive betting opportunities.
All bets on the Asian Handicap in live betting (including 1st/2nd half bets) are settled according to the score line. Any goals prior to the bet being placed are ignored for settlement purposes.
