It happen that you are just lucky by that time. You can only do that for few times. Results are completely random. I've used different strategies for how many years and I keep on using them until now, sometimes it works, sometimes or most of the time not. You hit it because you are lucky and not because it's the computer set up.
I'm about to believe on this strategies but after this reading the comment I guess it really works only base on your luck. Well, gambling is designed for lucky people and if you play without luck, the money will lose. So it means any computer set up will still not work, anyway will still this and hopefully to have some luck.
gambling is not only designed for lucky people because people that are not lucky can always play gambling . gambling is for everyone and not all who plays gambling are all aiming for the cash or for the profit but some of them are only playing because they want to past the time or they want to be happy a.k.a they treat gambling as a form of enterntainment and they dont care even if they will loose or not . its only thier incentive if ever they manage to win .
