Even regulated state lotteries do shady shit and are sued due to lying about odds and remaining prizes, and having seen first hand the way those and arcade games work.

I played some when they first dropped and the android playstore options were limited. You could see the bullshit weights first-hand if you had enough free pulls. Again, this, along with streamers doing massive pulls, and community-gathered spreadhseets are where I get my information, not from the game page that says '1 in 100 chance of legendary pull!' because, again, it's always been bullshit.
