www.mywebsite.com/listofgames/anyword/anynumber/anyword/mygamesname.html

Must be redirected to

www.mywebsite.com/listofgames/mygamesname.html

Answer 1

You may try this:

Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/listofgames/.*/([^\.]+)\.html/?  [NC]
RewriteRule .*    listofgames/%1.html                    [R=301,L]

Redirects permanently

http://www.mywebsite.com/listofgames/any/number/of/folders/mygamesname.html

with or without trailing slash.

To:

http://www.mywebsite.com/listofgames/mygamesname.html

Effectively removing the segment path between /listofgames/ folder and the HTML file.

String listofgames and extension html are assumed to be fixed, while mygamesname is assumed to be variable.

The incoming URL structure has to be kept for the rule-set to work: Last string inside the URL must be the HTML file.

For silent mapping, remove R=301 from [R=301,L]
