You are so right about those old slot machines not winning very often.
My ex-wife and I spent our honeymoon in Reno Nevada and we sat at this nickle slot machine for about an hour taking turns plunking in the nickles and pulling the lever.
After our first half hour, a couple doing the same thing on a dollar machine won a jackpot right up the row from us.
They said they had spent nearly 6 hours and close to $1,500, but they won just over $10,000!
Ok, now that's cool. Thirty minutes later, and about $50 in nickles, we hit a nice little jackpot ourselves for $100. We decided to take the winnings and leave.
The newer slot machines do pay out more often giving a player better game play and excitement with free spins and bonus rounds.
I do like the improvement of today's slots, plus it's much more sanitary (although you can still catch germs from the buttons).
