There should be a developed double or nothing game where you have 10 cards and you pay $100 more each time and 1 card is double 9 are nothing and you pick one if its double you win $200 and if you wanted to gamble again you only have to pay $100 unlike classic double or nothing but you keep getting double what you got last time so you keep getting profit if you win.But if you lose, you don't keep your combo therefor you go back to the start of winning $200,$400,$800,$1600 and so on.
