Editor’s Note: It seems a lot of people aren’t taking us seriously this week, as if our April 1st announcement of a puzzle app combining TomTom with 2048 and Threes! was just a joke. Today’s puzzle actually grew out of a past April 1st announcement that led to a real audiobook deal for our Grandmaster titles. This puzzle is a sample from Grant Fikes’ upcoming Cross the Streams audiobook. Listen carefully or you won’t be able to solve the puzzle.

Theme: Asterisk, Asterisk, Asterisk, ***
Rules: Standard Cross the Streams rules. Also, (as transcribed from the audio file): “You will hear the clues read to you, first the across clues (starting with the topmost row and moving towards the bottom) and then the down clues (starting with the leftmost column and moving towards the right). In this beautiful 10×10 puzzle, called “Asterisk, Asterisk, Asterisk”, grandmaster Grant Fikes has challenged the normal conventions of Cross the Streams, sometimes having two or more consecutive asterisks in a single row or column.”
Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.
