sure. its possible. when you are with your friends who also are trying their luck to the lottery, they do have input on what possibly the city are doing to cheat us. one example of the theory is that some of these table tennis balls are heavier and some are lighter. who can tell, we are not in the venue of where they draw those numbers. there are always theories.
There will always be people who will win the lottery no matter how much manipulation they are doing. I heard the balls that are being used in the lottery machine are being weighed live before the game starts only for the people to have a confidence that the game is fair but we can confirm it if we know someone who work inside it.
