Since governments own lottery are more transparent and people have more trust on them than the individuals one. Fortunejack is one of the most transparent and safe gambling sites and I think we have many other one and a trail is going to reveal to you. However remember that you can lose your investments in gambling.
Government lotteries are more transparent?
Are you aware of such cases like Triple Six Fix, Eddy Tipton, Milan Lotto / blindfolded children, Zhao Liqun, Serbian lottery scandal etc...
Even if you watch a draw on TV it does not mean you are not being cheated at the moment - refer to these cases...
Those are just some of well-known cases.
Blockchain-based lottery is the only truly transparent and independent lottery.
Any lottery where human factor is involved, including government lotteries, can't guarantee any fairness or transparency.
