Here are some information am able to gather after going through a search on the most gambling countries in Africa, am surprised at what i saw, to my greatest surprise, Nigeria being the least among other countries in Africa being listed, when i thought in terms of population and the likes should be the lead, many other underdeveloped countries and having more severe economy problem to have made their citizen found gambling as an alternative to livelihood, because i expected that Nigeria should still leading, which means, in Africa, We are far more better in many aspect.

This your proof of statistics might be wrong, because they might be doubt, for the statistics to say 65% of Nigerian participants in gambling, it's doubtable, because most population of Nigeria come from the north and I have not seen any northern who gambles especially their youths, so if census is being done to get the statistics accurately I don't think online statistics will give us what we wants, because I know very well that gambling is all about something they don't teach anyone, assuming the statistics is pointing at 40% I will agree because many people in Nigeria doesn't gambles and people that gambles very will in Nigeria are the southerns in Nigeria
