Let me atart off by saying that I love RTG games and their design.
I have a major problem with the cap on wins too. Don't see it is fair or necessary at all!

You
PAY to spin on all 25 lines of a slot and then if you are lucky enough to hit a huge win you only get paid for 5 lines! It's only a fraction off of outright theft!

I really for the life of me can't understand why this system is in place other than for the purposes of greed?
In Australia the slots in the pubs and clubs are capped at $10,000 per spin regardless of bet size etc... Wouldn't this be a fairer way for RTG to implement this system if they feel it is necessary to have?
Cap the wins at a fixed dollar amount per spin?
RTG should be refunding players for all spins where they have had to pay for 25 lines but those spins only had the potential to be paid out on 5!
Imagine if I bought a lottery ticket and won division 1 but was told 'Sorry, your win is capped at 50,000 times your bet' Instead of getting $2million I'd get $50,000
There are 10 games to a ticket as well so imagine if the 6 winning numbers were on game 7 but on game 2 I had won the $50,000 max cap. I'd lose my $2million prize as the game wouldn't count! There would be a public outcry if any of this happened and the people running the Lotto would be dragged over the coals!!
I really think the days of online casinos being a law unto themselves has to come to an end!
Incidentally, I believe that Australian casinos with slots do not have this max cap rule at all. Seeing as we play at 'online casinos' and not 'online pubs' then fairness would dictate that this max cap rule should not apply!
I personally have the max cap of 50,000 per spin running through my head every time I play RTG and it really kills the fun of the experience, diminishes the excitement that one gets from the excellent games and ruins the experience over all!
I really believe that RTG is succesful enough now as a software platform to remove the max cap function(or at least raise it considerably). I assume it is a selling point to casinos purchasing licenses to the platform to limit their losses but is entirey unecessary as the built in HE will win for them in the end. Having this rule is purely GREED!
In the end it also damages the image and experience of the excellent software as players dream of the 'Mega Hit', this is what keeps us playing, keeps us pumped up and pooring money into casino. The fact that RTG rob the player of this thrill entirely defeats the purpose of the games in the first place!

All IMO of course!
