With CastleVille's recent obsession with dragons, it only makes sense for the game's official forums to get in on the act by offering Crowns to those players willing to show off their dragons in their Kingdoms. In the game's new "Dragon Invasions Image Contest," you'll need to simply snap a screenshot of your Kingdom that contains at least one of the game's dragons: a Gloom Dragon, Ember or a Baby Dragon, and then upload it to the contest thread on the game's forums.

After May 27, Zynga will choose the top 10 entries, which will then be voted upon by players to determine the grand prize winner. The top place prize is 200 Crowns and the knowledge that the game's Facebook Fan page will sport your image for all of the game's fans to see. Two other random entrants will receive 40 Crowns each.

All told, this is another one of those contests that require very little work from you, but could pay off big in the end. Wish you the best of luck if you enter this contest yourself!
