How to make a parameter in url?

Question

PHP

Hello!
I have the following in .htaccess:

RewriteRule ^([a-zA-Z]+)/games/([A-Za-z0-9-?._]+)$ /games/index.php?lang=$1&name=$2 [L]

how can I make it possible to add additional parameters to the url, but not through htaccess, but directly in the address bar!
For example:
now I have a url like this: site.ru/ru/games/starcraft
how can I set the parameter like this:
site.ru/ru/games/starcraft?hideblock=true
where hideblock is the parameter that is passed $_GET request to the file /games/index.php
in /games/index.php I write:

<?php
$hideblock = $_GET['hideblock'];
echo $hideblock;
?>

and in htaccess I write:

RewriteRule ^([a-zA-Z]+)/games/([A-Za-z0-9-?._]+)?hideblock=([a-zA-Z]+)$ /games/index.php?lang=$1&name=$2&hideblock=$3 [L]

and nothing works!
can someone tell me how to make routing in php so that each parameter is not written in htaccess ??
Help me please!
