This is the website for the one and only official aka ran by the American Government for the green card lottery...

https://www.dvlottery.state.gov/

if you ever forget the above website you've been given by "goddess" try to remember to search for diversity visa, not for greencard lottery. I don't think there is a scam website which calls it by the official name. If you search for diversity visa the real websites pop up first.

Since the greencard lottery just closed you have to wait until next October in order to enter. Any website which promises you that you can enter any time is a scam.

the one with a .gov in the end is real

If there is a .com, .net or .anything else, its fake
