Subsoap is giving away Faerie Solitaire yet again on Steam as a April Fool's/Easter event.
Note:
-Only the first 10,000 people will be able to get it for free (so get in quick!)
-You must have a Steam account which is older than April 1st, 2013, and has 5 or more games in it (not sure whether they must be paid games or free ones).
-You'll need to join their Steam Community Group as well (you can opt out right after getting the game though)
It's actually a really addictive game, for those who haven't played it :)
It's a very addictive game.
There's a similar game on iOS for free, but it's much harder: Solitare Blitz
