I went to Berkeley back in the 90s and two of my physics buddies roped me into a similar scheme, except with blackjack. (They would discuss their latest ideas for string theory papers on rides to Vegas and describe their ideas to me. They knew that they were ready to start writing when I could explain their ideas back to them.) Anyways, they explained to me that cheating casinos was kind of like a rite of passage for graduate students in physics, and they treated it as "a proof of math". The thing is my buddies absolutely looked like physics nerds who were there to cheat the casinos - they absolutely did stick out like sore thumbs lol. So I remember our first time at Circus Circus playing blackjack - my buddies were up by alot, and then they just suddenly stop and leave the table at the top of their game. i asked why they stopped, and my buddy whispered to me that they had calculated that they were at the end of their run. The moment he said that to me, we noticed that like a third of the casino was staring straight at us. All the dealers, the janitors, a bunch of the guests, hostesses, everyone was looking right at us. And so we ran! Omg we got out of there so quick! Just bolted. That was our first attempt to do something like what happened in this video. Long story short, my buddies never made tons of money, mostly because the casinos automatically understood who we were (we suspected that we were on a list) and the dealer would do things like give us free drinks and ask us to solve random math problems while dealing the cards (which they would do while still keeping their counts!), but we had a great time that year! On our last momentous trip immediately prior to them getting their PhDs, my buddy told me that we will either come out of this with alot of money or a great story - and we got a great story.
