Star Battle by Thomas Snyder

[This is a repost from our archives with new notes at the top (original post here): Star Battle, which was originally designed by Hans Eendebak for the 2003 World Puzzle Championship, is one of our favorite object placement styles. The region constraints and no touching constraints lead to a lot of different logic. While there are computer-generated versions of this style in major newspapers now, the hand-crafted themes and logical flows of this puzzle are what we look for with any Grandmaster Star Battle.]
