Bingo

Bingo is already well-established as a branch of the egaming industry, and there are several niche operators who are doing nicely out of the growing interest in the game online. But as one bingo operator admitted to me recently, it is never going to be the next poker. However, it does have some strong attractions, most notably its ability to target a completely new audience of lower- to middle-income women. While this may remain attractive to women-friendly casino firms, ultimately it may prove too much work for too little reward for sportsbook and poker operators. It is not an easy cross-sell and may remain a sector where the bingo-only firms rule the roost.
In summary, if you are interested in a new demographic and a steady revenue earner this is a good bet. There may also be some uplift from rival operators spending money on educating the market.
