The Lucky bets are so named because of the bookmaker's practice of offering bonuses for one or more winning selections; most common of which is 'double the odds' for one winner. The offering of a percentage increase in winnings for the success of two or more selections in these Lucky bets is primarily to compensate for the compounding of the overround when two or more events with individual overrounds on their books are combined in doubles, trebles and accumulators.
