transferring items among several arrays in javascript

I have got a pretty complicated issue, I tried everything and its not working properly. So the conception is (i just copied the interesting part of it, otherwise it would be few hundred more lines) :

The program is a card game and 24 cards (4 different colors, one is always stronger,it is called ADU) are distributed randomly among 4 players (4 arrays). The table where you put down the cards are represented by "asztal" array. First the human player puts a card, then the computers should reach in this order:

1. If they have same color and higher value - pick that card
2. If they have same color and any value - pick that card
3. If they dont have matching color, any car from the special color set (for being simple, its the first card the loop would find in the array)
4. If they dont have matching color, nor card from special color set, than the first element of the array (player[0]).

If you run my code, you would see it is not grabbing 1/1/1 card from each array, but sometimes more. And those cards do disappear, and not getting into the asztal array. My code: (http://ift.tt/2gYKClN)

function CardA(name,value,adu){
    this.name = name;
    this.value = value;
};
function CardB(name,value,adu){
    this.name = name;
    this.value = value;
};
function CardC(name,value,adu){
    this.name = name;
    this.value = value;
};
function CardD(name,value,adu){
    this.name = name;
    this.value = value;
};
