If they are doing it, you could definitely make a strong argument that it's not necessarily wrong or immoral. Yet, I think many people would be very unhappy with that if they knew about it. Many already believe that the slots are designed in a way to make it as hard as possible to win, and knowing that the gameplay could change once a player moves up or down in stakes would add fire to the flames. Especially since gambling can be a very emotional experience for people and they often search for the "why" of what caused them to lose, even though the answer is usually simply that luck wasn't on their side today, or they're making bigger bets than they should be and underestimating the variance or the house edge.
While I'm still skeptical that this type of design is common in online casinos as the risks don't seem worth what looks like a very small reward - players could be unhappy if they found out and future regulations may disallow this behavior. And I wouldn't think the psychology of a low roller is THAT different than a high roller to make it a profitable difference, mainly the amount of money available. I certainly wouldn't be surprised if a few slot providers out there are doing it, but I've never seen any evidence of the big online providers doing that myself. (Someone who plays a slot often could notice if the reel layouts are different for example, though there's no guarantee anyone would notice.)
But I'm happy to agree to disagree. Thanks for your posts.
Well the different profiles within the same game is not something new its been around since early on.
Im not sure what risks your referring to and your statement is a bit contradictory on one hand you say "I think many people would be very unhappy with that if they knew about it" ( which more than you think probably already know or have suspected for a long time ) and on the other you say "as the risks don't seem worth what looks like a very small reward", if its such a small reward and dont really affect the player significantly then why would they be upset?
The fact someone has already said "It explains a lot of what many have experienced" might suggest that more people have noticed it before but never actually thought any more of it.
To me this method is no different to having say different reel strips for base games and free spins, some disclose this in the rules to the player some don't even when some games its blatantly obvious.
Its also no different to some games having 2 or more reel sets for the base game that are randomly selected each time with one set providing lots of 2 scatter near miss for example.
And no different to pick mes that have no impact on what the player gets, because it was pre determined, some are genuine some are not? but can you always tell?
You cant just focus on this one slot math method being a bit out of order when there is countless other ways players never get to know about.
"(Someone who plays a slot often could notice if the reel layouts are different for example, though there's no guarantee anyone would notice.)"
No they wouldnt as you only see the strips the designer wants you to see at spin effect time. Its called virtual reels. Example i might have KAAJTC on the virtual strip but the animated strip might only show KAJTC eg to player looks like one Ace but there is 2 doubling the chance, crude example but that sort of thing.
Slots are here to make money, the player is always going to lose long term, there is always creative ways to manipulate random game design in much the same way a player is always looking for a edge to manipulate the game.
I have no idea if its true or not but I was once told that the reason the stake profile change was used was to "protect" against advantage play, as although games are random, the probabilities should remain constant and in theory if a player knew the feature hit rate they could keep raising stake after so many games, so that when they hit the feature they will have been at a much higher stake than chasing on min.
So if the feature hit rate changes as stake goes up it could stop this potential advantage play in its tracks.
Of course its random and could still be risky for the player to do this without adding that, in the same way the martingale system on roulette isnt a sure thing, but I guess it could be a valid reason why it was / is used on some games.
A simpler example is if we played a game of throwing a die at 50p a throw if its 1-5 i keep your 50p if its a 6 i will give you 5.76x your stake. ( yes my game has a RTP of 96% coincidentally
)
If a 6 has not shown after 10 plays you telling me you wouldnt want to increase your bets until it comes? even tho its random and is no more likely to come next throw?
Keep upping bet till comes and if you advantage played correctly you would be in profit, you would be technically taking advantage of the fact its random and static probabilities are in play??
