Don't ever let anyone tell you penny slots are a waste of time. Hubby's best friend's mother plays pennies almost exclusivley and one day we were all out together and I was roaming and walked up behind her. She started with $20 and picked a machine and sat down.

In half an hour she cashed out over $100 and took $20 of it to the next machine. An hour later it was another $100 plus cashout and on to her 3rd machine. 10 minutes in it really started to feel good so she started upping the play a lil each spin and then WHAM!

She hit the progressive (til then I didn't even know what THAT was) jackpot on max bet and from a bet of what? 15cents or something she got a $15,000 win. I was standing there with my jaw in my hand so it wouldn't hit the floor. AND - I am told she hits one every other month or so like that, although I was only there to see that one.
