The bet spread is fairly narrow at $2 up to $50 in $2 increments, so the poor schmuck betting a martingale would quickly run into the maximum bet. I don't know if this is normal for charlie rules but the dealer also stops after drawing 6 cards so if you stand on 16 and the dealer draws 6 cards to 15 then you win. The rules are single deck, shuffle after every hand, dealer stands on soft 17 and peaks for BJ, BJ pays 3:2, double on 9 10 11, no surrender, split to 2 hands only, no double downs or BJ after the split but you can hit split aces, and a 6 card charlie to boot. It is made by Pot O Gold and named Black Gold 21. I have been playing a video blackjack game at Harrah's Cherokee in NC which should have a small player advantage using optimal strategy if the cards are truly random.
