Are you taking history lessons from a Monkey? Blackjack was an unpopular game? Relax, take a deep breath and compose your thoughts before you respond. I'm not sure where you learned what you are writing, but it is wrong. BJ was the most popular game in Vegas in the 1960s, and became semi-unpopular after casinos changed the rules after BTD came out. Before that, it was single deck, dealt to the last card, get a BJ after splitting and it paid 3-2, ect,ect.
