How to make pretty url for SMF pages?

[GleamPlay.com]

I have 2 pages which are "index.php?page=iogames" and "index.php?page=leaderboard"

Is it possible to make a direct link to them as "/iogames" and "/leaderboard" ?

Thanks!

Those look like portal pages and, if so, you'd need to ask on the portal's support thread (or, in SimplePortal's case on their site:  SimplePortal.net).  If not, have you tried this?
