I think casinos using such a rule should be named and shamed in so many places and forums that no player in its right mind would ever want to play there.
Casino Triomphe is one of these so STAY FAR AWAY from it! (I think there are a few more using Rival and Top Game software.)
What I find particularly interesting is that Casino Triomphe (which seems to be a sister site of Euro Moon and ParkLane, with the exception that Euro Moon and ParkLane do not have this particular outrageously predatory term) have
NETent games,
Novomatic games, BetSoft games, NextGen games, Amaya (Chartwell) and
Gamescale (which was known to be a proprietary software used exclusively on Conan Gaming casinos). So I believe there is a strong connection between Casino Triomphe, Euro Moon, ParkLane, Deuce Club, Osiris and Cosmika Casino.
If you have any info about ANY casino using the same (or a very similar) term, please name and shame the casino in cause here in this topic thread and I am sure that someone from Gambling City will take care to list that casino in
Gambling Citiy's WARNING TO PLAYERS list.
