Regex rx = new Regex(@"http://www\.sokoban\.com/games/(?<captureThis>.*)",
RegexOptions.None);

Match m = rx.Match("... your text here ...")
string result = "";
if (m.Success)
{
result = m.Groups["captureThis"].Value;
}
return result;

You might also want to consider usign the Uri class or System.IO.Path they're
both very good at extractign parts of an URI. And probably a bit faster and
easier to maintain over time.
