GCHQ Christmas Card Puzzle 2015 (Part 1)

 

A Christmas card with a Cryptographic Twist for charity.

 

This year, along with his traditional Christmas cards, Director GCHQ Robert Hannigan below is including a brain-teasing puzzle that seems certain to exercise the grey matter of participants over the holiday season.

 

 

 

The card, which features the 'Adoration of the Shepherds' by a pupil of Rembrandt, includes traditional Christmas greetings from the Director on behalf of the department.

 

 

However, unlike previous years, the 2015 card will contain a grid-shading puzzle and instructions on how it should be completed. By solving this first puzzle players will create an image that leads to a series of increasingly complex challenges.

 

Once all stages have been unlocked and completed successfully, players are invited to submit their answer via a given GCHQ email address by Sunday 31st  January 2016. The winner will then be drawn from all the successful entries and notified soon after.

Players are invited to make a donation to the National Society for the Prevention of Cruelty to Children, if they have enjoyed the puzzle.

 

Getting started....

In this type of grid-shading puzzle, each square is either black or white. Some of the black squares have already been filled in for you.

Interactive Puzzle

 

Each row or column is labeled with a string of numbers. The numbers indicate the length of all consecutive runs of black squares, and are displayed in the order that the runs appear in that line. For example, a label "2 1 6" indicates sets of two, one and six black squares, each of which will have at least one white square separating them.

 

Clue

Puzzle Grid 25x25

First Column 7,2,1,1,7 (7 black, 2 black, 1 black, 1 black, 7 black)

Note: You will have to work out the number of white squares after each set of black squares.
