I recognize the gambler in me. While I could control it, if I'm in front of slot machine I might spend more than what I said I would. There must be that gambler gene in all of us that makes us believe that the next bet will bring us the jackpot.
With the opening of a casino in my city, thought about looking up these articles.

The Psychology of Gambling
While most of those articles talk about how the casinos lull you into staying longer and playing more, the 3rd one has a few intersting tips.
1. Slots that pay more can be found in more popular sections where a lot of people can see you win. Stay away from obscure ones. Might try this tip the next time I visit. Fingers crossed.
2. Read the pay table. If there are a lot of combinations that return wins, this might have a higher win frequency.
3. Check the pay ratio.(This is why I always bet the lowest but with more lines.)
Location of Loose Slots
Another interesting site I've found. This might work on big casinos in las vegas. Lost some money when I went there. I don't think I won there at all. I don't know if it will work in our local casino but it's quite interesting. Still with the same concept - more wins to attract more people to play.
EDIT: 6/29/12 Tried the location trick... didn't work for me.
Going to try the time trick next time. Or maybe it really is just a matter of chance. lol
