Use this .htaccess (put it in the root folder of your site, else it will not work):
Code:
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^games/links.html$ /index.php?action=links
RewriteRule ^games/contact.html$ /index.php?pageid=2
RewriteRule ^games/advertise.html$ /index.php?pageid=1
Should do it
