Web in the Window?

[Stinkerbell]

Someone in a room was talking about a Spider Solitaire challenge called Web in the Window or something like that.  I usually buy all the challenges, but this one is not in my albums.  Anyone know when it was offered and is it still available.

Its the mix n match badge that you have to win 18 games on hard difficulty. It is my mix n match #4 album so if you have bought all the gem badges, maybe look there.
