It is interesting to work out the economic logic behind Betfair’s Zero Roulette. Essentially they are making a loss on the game. Professional systems players aside, there are operating, marketing and personnel costs to running Zero Roulette. So how come they don’t go broke? Well, the removal of the zero helps players immensely but it doesn’t automatically give the players an advantage. There are probably masses of players who still play without any roulette strategy or understanding of the game. But the real reason is that it gets new roulette players on their books who might also gamble on their betting exchanges. Betfair is currently the market leader and dominates online horse and sports betting. The betting exchange is where Betfair makes its profits. So much profit in fact that they are willing to burden the costs of Zero Roulette if it means a chance at getting new players on their exchange and gives their competitors in the online gambling business a hard time. It is impossible for any other online casino offer Zero Roulette without a hugely profitable side business. In the long run, Zero Roulette is probably going to be banned for being unfairly uncompetitive to other online casinos. In the meantime, you should exploit the competition between online casinos and stick to Zero Roulette while the good times last.
Good Luck!
