In sports betting there is a specific practice used by bookmakers where they offer bonuses for one or more winning selections, generally referred to as Lucky bets. The most common of this type is the double-the-odds bet for one winner, where the offering is a percentage increase in winnings if two or more selections of these Lucky bets can exponentially increase to compensate for the compounding of the over-round when two or more events with individual markers are combined. This is a type of full cover bet, which is really nothing more than a wager made consisting of multiple bets over a given number of selections.
Since sports betting is so complex, there are a variety of betting processes used. Full cover bets are used in sports betting by companies such as Ladbrokes and William Hill to cover specific odds. Selections of this can include Trixie bets, Yankee bets, Patent bets, or the aforementioned Lucky series. For example, Trixie bets are full-cover bets made in sports betting where an individual makes three selections in different events, with four bets being used: three doubles and a treble. In order to get a return off of the Trixie bet, two of the selections have to win. A Yankee bet is a wager on four selections using 11 separate bets: six doubles, four trebles, and a fourfold accumulator, with a minimum of two selections required to win in order to gain a return on your initial bet. This is a very complex way to participate in sports betting, and is generally reserved for veterans.
