Dutch intelligence service AIVD released its annual Christmas Puzzle challenge. This year's challenge is 12 pages long, consisting of smaller puzzles that can be solved individually. Solutions can be submitted to the AIVD up until January 16th, 2017.

Due to the popularity of the annual puzzle - the AIVD received 16,000 submissions last year - the service this year also added an answer form, to make it easier for the AIVD employees to check the answers on the submissions. Only submissions on the answer form will be checked. 

Each correct answer will get you points. And the person with the most points wins the now traditional trophy. Each person that answered at least one question correctly will be sent the answers during the course of February 2017. 

"You may of course work together, but we encourage you not to use more than four persons per team." the AIVD says. "We also explicitly ask all participants not to exchange answers on public forums before the last minute of submissions."
