Press Hit for another card and stand if you don't want any more cards, face cards are worth 10 points ace cards are worth 1 or 11 points, and cards with numbers on them are worth that many points, it says how many points you have in the top left your goal is to get 21 points but if you go above 21 you lose, once you press stand the dealer will draw more or reveal his points if the dealer has more points than you he wins and if he has less you win if you both have the same amount its a tie and whoever reaches 21 first wins.
