Don't play those games where your chance's of winning is very low.I always avoid roulette,slots and keno because these game depends on luck mostly and house has much advantage.Try blackjack, because it's depends on your skill mostly.
You are totally wrong on this, blackjack is just another game of luck and you dont need any skill for this game as well. Either way , all game have house edge so your only chances is either to choose the game with the lowest house edge or even the one that is actually EV+ however doing this wont be really possible if there are no promotions for the site
