Dear Mark: Any time I start playing slots, I always seem to win at the beginning, but end up going home a loser. I should just quit while ahead, but I do not because it takes me an hour to drive to the casino, and I do not want to play for just 15 minutes and leave. Is there any chance that the slot machine senses a new player has not been at a particular machine for a specific period, and then pays off initially, then stops paying? Joy C.
First off, Joy, slot machines do not have an onboard motion detector or operate with artificial intelligence. Slots are preprogrammed to pay out a certain percentage on a random basis with streaks — both good and bad — appearing at any time. The slot machine doesn’t reason that “Let’s give Joy a bunch of loot on the front end so that after we’ve hooked her, we’ll snag all that money back.”
The grind is that the casino is capable of eventually winning your entire bankroll due to the huge built-in advantage it has over you when you play slots. And your willingness to keep playing these cybernetic one-armed bandits is the reason you will eventually be relieved of your hard-earned money.
Actually, Joy, when you begin playing, it doesn't take much to prove a winning session because you have not been playing long enough to lose a sufficient sum of money to the machine — at least, not YET.
That doesn’t take away from the fact that slot machines are rigged – I think that’s a good word – so that they pay back less money than you invest in them. Therefore, Joy, the longer you play, the more likely you are to give back whatever winnings the machine provided you at the outset.
By the way, Joy, I believe you might be the victim of of selective memory here and somehow seem to have forgotten all those sessions that you struggled from the get-go, where you never did get ahead.
Another factor, Joy, is that the casino knows that you, as you stated, won’t stay for just 15 minutes and play through your money just once, but keep playing your credits over and over again during your stay. So, for example, on a 93% return machine, if you were to play your entire $100, you can expect back, “in theory,” $93. Of course, the casino anticipates your playing the $93, so expect a return of $86. Put in the $86, and your return will be $80. Play through the $80 and you will get back $74. Can you see, Joy, how the casino is grinding away at your initial $100, and why coming home a winner after a lengthy session is an unlikely outcome for any slot player?
The bottom line here, Joy, is that the result of every spin is an independent event. What is for sure is that you lose less money when you play for a shorter time, but a shorter timeline is no predictor of winning.

22 April 2016Dear Mark: The Michigan Lottery offers a game called PokerLotto. It includes a draw poker hand from the machine against a poker pay table. Then, there is a 7:30 p.m. drawing in the evening where if the cards on your ticket match the exact poker hand shown on TV, you win $100,000. My question regards the second chance of winning. ...

8 April 2016Dear Mark: A book review in the Wall Street Journal appears to claim that a computer can win at roulette. This doesn't appear to be reasonable, since each spin should be random and the rules of probability favor the house quite strongly with the normal double-zero American version. In the comments, someone ... (read more)
1 April 2016Dear Mark: When it comes to blackjack, why is counting cards considered a form of cheating? I look at it as someone who is very good at the game and no different from someone playing poker, like players who are very skilled at bluffing and reading the body language and facial expressions of the others at the table. ...
