So ideally the machines in the slot casinos games are configured on some feasible winning and some of loosing?
I am not in doubt because there are actually strategies you may apply while using a particular computer system while playing the slot and you won't win and same techniques could be applied when switched over to another computer system and you could win.
From there some players would always assume their luck to be on that particular computer system. So at their unaware some reconfigurations would be done over night where the player comes other time can not be possible to win ahead like the other times.
Can't be determined because it won't be confirmed by any gambling provider in particular with slots. But I doubt there's a strategy with pure luck based games like slots and dice games simply because outcomes are in random pattern. Although some would claim for algorithm but it's not simple as that. Perhaps we would believe that there's this cycle in slots for winning and losing attempts; how will we decode this pattern then? Slots provider won't just allow such information to leak easily and they'd know if ever some people are continuously winning which will make them create changes with the existing algorithm. However, whether it is really programmed in such way or not, luck will still play things out unless you'd play every slot attempt or if there's a way to monitor the 'cycle'.
Yes, that's the basic of slots. They won't install those machines or game developers create online slots if there's no real profit behind it. As I said on other threads, the only winners in gambling in casino games are those who won a good multiplier and then quit afterward, never coming back anymore even just to try their luck again.
Winners are rare for machines that are created by humans to make a profitable income for them. Online gambling sites will also go bankrupt if they enter online slots that are like charities giving away money to gamblers.
There was once I got lucky on an online casino application in one slot provider and the next day they went to maintenance and I never won a good amount again. They will just keep tweaking the system if they see some gamblers winning.
Whether slots are rigged or not, they'd be having profit from other bettors especially those who are losing. Of course not all players would win, which means profit is most likely to take place for the gambling providers. Not all providers are tweaking their games intentionally. There are still fair platforms and if outcomes are not going along with your expectations, you could just move with other gambling games to try your luck out.
