It's math, they are offering you a percentage of the winning, they are not risking paying way more than that, and at the same time, they don't have to deal with customer hedging their bets. It might sound like the bookies are giving you more chances but in the end, it's a thing of probabilities so in the long run with thousands and thousands of games they will still win the same amount.
Lol, no! At most, they offer a new feature to tempt you into taking huge odds combinations in the hope of picking the winning ones first and the losing ones at the end of the ticket.
