public function play($wheel) {
        if(!isset($_POST['nonce']) || !isset($_POST['id']) || !isset($_POST['action']) ||
           !isset($_POST['seq']) || !isset($_POST['pseq']) )

        if(empty($wheel))
            $wheel = Wheel_service::get_wheel($_POST['id']);

        $current_play = Wheel_service::validate_sequence($wheel, $_POST['seq'], $_POST['pseq']);

        if(!is_int($current_play))

        $segment = Wheel_service::calculate_segment_hit($wheel);
        $winning = $segment->type != 0;
        $wheel->plays_left = 0;
        $is_last = true;

        if(Settings_Manager::get_setting('log') === true)

                $winning? 'They hit "' . $segment->label . '", with value "'.$segment->value.'"' :''
            ));
