I played at JPP for a short while but quit doing so.
Reasons already mentioned like the lower average RTP on the slots because a chunck of the stakes go into this jackpot system.
Personally I don't like casino's where they lower the payout of slots in favour of an added jackpot.
I love WMS slots and they are challenging enough on the normal RTP settings and on JPP they are extremely hard to win on.
For example,I like Jungle Wild and played it at several casino's and the free spins hit quite fast but I never managed to trigger them on JPP in like 500+ spins.
And I had same experience with other slots like Ruby Slippers and Zeus,some of my favourite WMS slots.
They seem to play very tight at JPP.
Also I hate the chat option as even if you turn it off it seems to slow down the functionality of the website.
If you play a slot and turn off the chat it sometimes still responds very slow or there is a bit of lag on the spins.
Totally unnecissary,a chat option.
We are not babies like and if I am gambling I am not looking to chat with people really lol.
The chat moderators come with these stupid mini games where u can win a few quid or some free bingo cards and throw around these stupid messages filled with lucky dust and that kind of sh*te.
Like I said,kindergarden for grown ups.
And last but not least,the conversion rate for € to £ is very bad,always was so not even worth for me depositing as I have no options to select deposits in €.
I understand they are accredited,they do pay IF you win etc etc but defo not my cup of tea.
One of those "social" casino's like Jackpotjoy,another casino with chat option and lucky dust sprinkling chat ops to keep players depositing while slots play very very very tight.
Just my 2 cents.
