[Solved] I write this script. Unfortunately, jQuery console throw:

Error: cannot call methods on dialog prior to initialization; attempted to call method 'open'

I use jQuery 1.10.2 and jQuery UI 1.10.4.

 $(function() {
$("#player").on('click', 'img', function() {
    var zadanie = $( "input[name^='act']:checked:enabled" ).val();
    switch(zadanie){
        case '1':
        alert('fajowo jesteś uczciwy');
        break;
        case '2':
         $( "#dialog" ).dialog( "open" );
        break;
    }
    });
});

Dialog in HTML:

<div id="dialog" title="Wybór karty, która zostanie położona oficjalnie">
<p>Fajowy tekst.</p>
</div>

You have to initialize the dialog before being able to open it:

$(function() {
    $("#dialog").dialog({
        autoOpen: false
    });

    $("#player").on('click', 'img', function() {
    ...

Here's a complete example: https://jqueryui.com/dialog/#animated
