I will say that you can still have fun playing online though certainly your $ might not last as long as it did a few years ago.
If you stick to reputable casinos you will probably have a "winning" session sooner or later.
I normally throw out some numbers and play data in these type of threads but I know that turns a lot of people off and they can not relate to how that translates into their gaming experience so I will just talk in general terms about my slot play experience and other people can decide for themselves if they can relate their play to it at all.
What frustrates me is the streakiness of all the software I have played.
Some are less streaky than others but these unnatural cycles still occur.
What is unnatural about winning and losing streaks when gambling you may sensibly ask.
What is unnatural are the huge upswings always followed by huge downturns in the RTP and how this manifests itself in the play data.
So you may be hobbling along over many deposits getting around 85% RTP for example when one day, happy, happy all your favourite slots suddenly throw out retriggers a plenty and wins of x 50+ are suddenly fairly common where as conversely you hit only one in the last dozen deposits, duh?
If you carry on you will eventually hit the ceiling of this streak and pow!
You won't just start getting the 85% type play again and lose slowly you will get closer to 50% and every slot that was throwing wins at you is suddenly dead.
Slots where the scatter (feature trigger) and wild double as one symbol are very obvious as you may not see the scatter/wild symbol on reel one for an eternity (3 stop positions that are suddenly and magically impossible to hit)
The other reels are not much better though you may hit reel 4 and 5 together to pay a scatter win.
You will be going several hundred spins between triggering features and shock and surprise they pay next to nothing without a sniff of a retrigger.
Each software and slot has its own idiosyncrasies but the general pattern will be the same but because the software retains a random element you will always get the odd blip in either a win streak or death streak - however if I check my optimum RTP and results then the RTP and results from there against my "average" session I will see they are quite anomalous.
Just recently (in the last week) I have had streaks on both Playtech and MG software that fit this pattern exactly and have repeated it many, many times over the years.
My feeling is the upswings are not as large as they used to be and the downturns are are more brutal and last longer.
That would be a natural occurrence if the slots were weighted and/or the RTP generally set lower than it was in the past.
Now at some Casinos I seem to never hit and always get below expected results while at others I will get these streaks from time to time.
At some Casinos (including only casinos I have played many deposits) I will be at around low 90's percentage wise and at others around mid 80's or even lower.
Am I getting a fair game?
The answer is probably yes at some casinos and no at others but how can you trust software that does not need to stipulate the RTP for any given game on any given day?
Because their RNG has been tested? No
Because they are licensed by Kahnawake or Coata Rica? No
Because they are licensed by Alderney or Gibraltar? No
Because the Casinos can make as much money at 98% RTP as 85%,No
(Don't anyone ever bring this stupid argument up again for why Casinos are fair, please!)
The reason I added respectable whitelisted jurisdictions is because that while you would be much wiser playing at Casinos licensed by these jurisdictions they do very little ensure that the games are always the same RTP and nothing at all about them being weighted.
For example after initial checks and a license is granted by Alderney how proactive do you think they are?
Well they check the audit results of their Casinos once a year - and that is it!
Otherwise they will only investigate complaints.
There are no such things as random checks on the software - not according to the email reply I received from them.
So if these slot designs and games are legitimate and the RTP alterable even by the best regulated Casinos what goes on at the other end of the scale?
I suggest you write to whichever whitelisted jurisdiction your favourite casino is licensed by and ask them specifically what they have done, where and when in the last 12 months to ensure the integrity of the software and RTP of the games.
See if that brings you any comfort.
Ultimately you can still have fun at remote casinos and I seriously doubt any top brand Casinos would even consider using rigged software (so unlikely I pretty much dismiss it) - so stick to low stakes make these casinos your home but don't just put up with poor or anomalous results.
Even these Casinos have different RTP settings.
Nothing will ever change if we just accept this is as good as it is going to get.
Stay safe, have fun.
