I have integrity concerns regarding their own software Blackjack games particularly the game American Blackjack Turbo. I am unable to find the software provider behind this game. There are no RNG certificates or anything proving it fair. Under normal circumstances the game should have an approximate RTP of over 99%, however after betting over 6000 EUR the RTP sits at 89%, Furthermore the game shows extremely awkward patterns such as you betting large, having 20, dealer 5 and he pulls 21. Within a very short timeframe today I lost around 800 EUR on this game. I find that extremely strange having played Netent, Microgaming and other BJs. It is not the losing but the how. The game also runs in very strange streaks. I demand that Drueckglueck supplies all information regarding this game and depending on the outcome I will consider further steps. At the moment I feel totally defrauded and I want to warn other players to play this game and possible also not play at Drueckglueck.
