Stretching is a process when the bet odds are raised to the fixed value of the odds - then the company can achieve the same effect when the fractional odds were used. In this case odds become higher and the max win value grows. The higher odds are called stretched odds with its stretched bonus.
Some values of the odds are not stretched because there is no reason to raise it to the fixed value. Stretching is applied only for the odds values which are taken from the stretch table. Odds stretching is determined by using decimal odds format and shown by using the Honk Kong odds format. Decimal odds are calculated: decimal odds = Honk Kong odds + 1
Odds can be stretched only at the Horse Racing games when the bets of fixed win and fixed place bet types are selected. It is important that odds will not be stretched if cross betting is used (for example, a punter wants to place a bet from Horse Racing and Lotto games at the same betting slip. The odds of the selected bet options should not be stretched).
Odds stretching can be set through the Admin website. Login to Admin system, go to the Management tab, select your organization, in the main settings scroll down until you find setting 'Stretch horses odds'. You can enable this setting when editing configuration of your organization.
