Best way to win in the past was to be a slot machine lurker. With the new computer controlled ones that can be modded remotely, including the payout ratios and amounts, you wont win.
Now the best way to come out ahead is to count cards on blackjack. And eventually the cameras will notice this and they wont let you play the tables after that.
They can’t be controlled remotely. They are preset to pay out whatever the minimum return the state sets, usually 93 to 95% of what is put into the machine. However, that’s over the lifetime of the machine which is estimated to be up to 10,000,000 “pulls.” The machine will reset towards the end of its life, which is set by the manufacturer, and start paying out either more or less in order to meet its preset goal.
The moment you walk into a casino facial recognition kicks in. Your entire history is there, games you’ve played, money spent, etc. If you’ve been caught counting cards you’re marked and trespassed from every casino with the facial recognition system, nation wide. Practically everything you do is on camera and recorded. Every employee is under the same, especially dealers and cash cage. I worked casino surveillance for a while and was shocked by the level of technology and lack of privacy. The level of detail is very fine. I realized this is the future of everyone under the UN and AI.
