我改變了那里的一些東西，使這對你有用。

var colors = ["Aqua", "Black", "Blue", "Brown", "Coral", "Crimson", "Cyan","Fuchsia", "Gold", "Gray", "Green"],
    colorsText = colors.join(', '),
    target,
    guess,
    guesses = 0,
    tries_allowed = 10;

function play_game() {
    var random_number = Math.random() * (colors.length - 1);
    target = Math.floor(random_number);

    make_guess();
    return;
}
function make_guess(){
      guess = prompt("I am thinking of one of these colors:\n\n" + colorsText + "\n\Which color is it?");
      guesses++;
    if (!(check_guess(guess)) && guesses < tries_allowed) make_guess();
    return;
}

function check_guess(guess){
    var guess_index = colors.indexOf(guess);
    if(guess_index === target){
        alert("Congratulations! You have guessed the color - " + colors[target] + "!\n\nIt took you " + guesses + " guesses to finish the game!\n\nYou can see the color in the background.");
        return true;
    }
    if (guess_index <= -1) {
      alert("Sorry, I don’t recognize your color.\n\nPlease try again.");
      return;
    }
    var hint;
    if(guess_index < target) hint = 'lower';
    if(guess_index > target) hint = 'higher';
    alert("Sorry, your guess is not correct!\n\nHint: your color is alphabetically " + hint + " than mine.");
    return;
}

play_game();

我希望這有幫助。
