I agree with you about some states manipulate the outcome, but there clever about it, and yes there certified, but some machines have different draw patterns, also they change out ball sets, and mix them daily, perhaps in the name of randomness, or the pretense of making sure they work. but compare the outcome of win totals and you see a pattern. Yes the lottery adds to education, but it also pays top execs. Big bonus. and as far as I know there’s nothing you can do but complain , and or play elsewhere.
