Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^game\.examplemysite\.com [NC]
RewriteRule ^game.+$ http://game.examplemysite.com [R=301,L]

Code (markup):

That will redirect all requests for http://examplemysite.com/game to http://game.examplemysite.com

 

Many Thanks...
