Maybe they'll make her an offer of two million (with a confidentiality clause to go with it) and then change their machines to feature a prize figure on the screen along with the warning...in big letters..."all prizes subject to verification".
From all the Jackpot screens posted on youtube, you can see that is not how you are notified. But can they explain why this screen appeared?
You cannot enter a few dollars —no required symbols appear, no multiple free gam bonus happens — screen suddenly has that message.
No game in AC or Vegas will give you that much. Unless long running Progressive Jackpot. See my previous posts .
