    Default Please help with my blackjack javascript game

    Ok basically i am making a blackjack game and so far i have a random generator for my cards, once i press deal 4 cards are dealt at random, but when i try to insert a new button for the player to press for another card "hit", the card comes down and is not random at all. I could really do with this help. Thank you.

    If you'd convert it to a java program, there would be more chances of someone helping.
    If you don't understand my answer, don't ignore it, ask a question.
