So besides the code being obfuscated and unreadable there are a couple of errors.

One problem is the curly braces such as ″ , “ and ” . They should all be replaced with either " or ' .

Then the first line declares a variable _$_d9ef which later the code tries to access as $_d9ef and $d9ef and _$_d9ef , of which only the last access will work and the rest will fail.

The final executable code would be

console.info("Activated script");
Number.prototype.Crop = function(x) {
    var s = this + "",
        a = s.split(".");
    a[1] = a[1] || "";
    return parseFloat(a[0] + "." + a[1].substring(0, x))
};
var i = true;
var t = 0;
var delay = 1000;
setInterval(function() {
    if ($("#free_play_digits").css("display") != "none") {
        t++;
        if (delay > t && $("#free_play_result").css("display") == "none") {
            $("#multiplier_first_digit").html(Math.floor(Math.random() * 10));
            $("#multiplier_second_digit").html(Math.floor(Math.random() * 10));
            $("#multiplier_third_digit").html(Math.floor(Math.random() * 10));
            $("#multiplier_fourth_digit").html(Math.floor(Math.random() * 10));
            $("#multiplier_fifth_digit").html(Math.floor(Math.random() * 10))
        } else {
            $("#free_play_first_digit").html(1);
            $("#free_play_second_digit").html(0);
            $("#free_play_third_digit").html(0);
            $("#free_play_fourth_digit").html(0);
            $("#free_play_fifth_digit").html(0);
            $("#winnings").html($(".br_0_0_5_0")[0].innerHTML.split("")[0]);
            if (i) {
                i = false;
                var number = parseFloat($("#balance").html()) + parseFloat($(".br_0_0_5_0")[0].innerHTML.split("")[0]);
                number = number.Crop(8);
                localStorage.balance = number;
                $("#balance").html(number)
            }
        }
    }

    if (i == false) {
        $("#balance").html(localStorage.balance)
    }
