Does a slot machine know the amount of money that is deposited at the start of play for a person and does that have any bearing on the percentage of payout?
Let me start with your second question first. The amount of money you deposit into a machine has no effect whatsoever on your results. ... (read more)
Ask the Slot Expert: More found ticket woes18 July 2012
Hi,
I found a ticket for $98. I picked the ticket up and told my brother what happened. I was so excited I told him to cash it so we could play again. While I was playing security asked us if we found a ticket and said we could be charged with a crime if we didn't pay it back. I had already cashed and spent the lost ticket money at this point. ...

Here is the simple answer.
It is true that computers use pRNG technology to generate random numbers.

Ask the Slot Expert: Concerns about pseudo-random number generators4 July 2012
Slot machines really have pseudo-random number generators (pRNG). A pRNG generates a number stream that appears to be random and satisfies many properties of randomness, but is actually generated by a deterministic function and is not truly random. Ron was right. Strictly speaking, the results on a slot ... (read more)

Ask the Slot Expert: How do slot machines detect a new player?27 June 2012
I have been playing heavily for the past 4 years and I have noticed that virtually all of my "big" wins ($500+) happen within the first few spins.
I have not been able to "force" a machine to win by playing long periods at the same machine. Given this, I am now of the opinion that if you play a machine ... (read more)

John,
I am a regular reader of Casino City Times and enjoy your slot expertise. Previously, you answered a perplexing question for me, and I thank you.

Ask the Slot Expert: Slow machines in a slot tournament13 June 2012
John,
I’ve been playing the slots for decades and have been in more slot tournaments than I can remember. For slot tournaments that are time-based rather than credit-based (most of them I think), I have always thought, “He who can hit the spin button the fastest generally gets the most spins.” The ...

Ask the Slot Expert: Do casinos replace machines to change paybacks?6 June 2012
I heard that casinos have to post the percentage changes on a machine if they change the payback, but they can get around this rule if they put in a new machine.
Is that why they choose to replace the machine?
I am not aware of a jurisdiction that requires a casino to post a notice on a machine if it ... (read more)
Ask the Slot Expert: Treat tickets like cash30 May 2012
This is what happened after I cashed out on a slot machine.
I had won $787. I was going to get my money from the cashier, but the casino announced an emergency and everybody needed to evacuate. When I got near the exit door, I placed my ticket in my fanny pouch.
The next thing I know, a girl elbowed me. ... (read more)
