For a long time now I've been reporting here, and in my "PlayTime Las Vegas" blog, about the continuing rise in popularity of the penny slot machine.

There are a lot of reasons for this, and here in Las Vegas the penny slot machine has always been popular among the retired set, for mostly economic reasons.

But for quite a while they have been the biggest money maker in many a casino because they tend to pay out at slightly higher percentage rates in some casinos.

This long time Las Vegas casino love affair with the penny slot machine is now spreading to other parts of the country and this has caused a whole slew of interest in these machines.

The majority of the questions center on how these machines pay out and here's where you can learn about what makes a penny slot machine a penny slot machine and their unique "bonus spins" and "multipliers."

Have fun and good luck!
