Slot Machine with Advertised Probabilities

I recently read that slot machines account for approximately 80% of the total revenue for the average casino. So much money at stake for casinos and yet they seem to make such a meager attempt to lure you to THEIR slot machines instead of a their competitors’. Sure, large jackpots are nice, but everybody knows that the chances of winning them go down proportionally to their size. People who play slot machines are not necessarily behaving rationally, but they aren’t stupid either. I’m sure that if it was well known that slot machine X has the best odds in the house, people would flock to it, even if its odd were still far worse than 50-50. What’s more, people would be far more inclined to make higher bets in it (play full coin). Following this logic, the casino has an interest in advertising this fact with neon lettering and flashing lights so everybody knows about it. Perhaps even placing a prominent plaque listing its odds and comparing them with other popular slot machines. Assuming that there is no casino cartel and that the mafia doesn’t burn down the building (who would even think of such a thing), the laws of economics predict that with an informed (efficient) marked, you will actually make a larger net profit, despite the fact that fewer people will now use the “regular” slot machines.
