No one in this entire thread has even mentioned this!
It would be very hard work to analyze the numbers and find where the house doesn't have an edge.
This has happened before, even with the lottery. Purchasing a certain amount of tickets, if enough money was put in it, statistically returned more money.
The ROI was more than 15%

Go in there "to gamble" spend almost no money, try to find a game that returns most of your money, enjoy free services.... Leave
Rinse and repeat at another casino.....
Maybe you can just do math on how to beat their games while drinking free water and enjoying free AC and music and then go on your way.... You saved money on AC and accommodation, you beat the odds.
Basically you have to be a parasite...
Working hard to find out how to cheat also works.... If you could somehow rig the jackpot, that would be very hard work and the ROI would be ludicrous.
Any gambling business or casino that didn't have favorable odds would quickly go out of business. I'm shocked that a lottery was actually in favor of the players in that case you posted. In traditional gambling the house edge isn't that high but the government run lottery has absolutely terrible odds.
