Assassin’s Creed 4 Black Flag Abstergo Hacking Puzzles

Hacking can be carried out in a number of ways which requires you to solve certain puzzles to carry out a successful hack. The game features Sphere Puzzles, Prime Number Puzzles, and Data Stream Puzzles.

In Sphere Puzzles, you need to reach the one of the two Green Lines by moving the Blue Data Avatar. There are no particular solutions for Data Stream Puzzles but we would ask you NOT to rush through them as these a lot of time and patience.

As for the Prime Number Puzzles, there are a few things which you should keep in mind before going for the solution.

  • Last digit (even number) = Multiplier of 2
  • Last digit (odd number) = 2 will NOT be a part of the solution
  • Last digit of the sum of numbers equal to zero = 2 and 5 will be in multiplier
  • Sum of the numbers indivisible by 3 = 3 will NOT be a part of the solution
  • Sum of the numbers divisible by 9 = two multipliers are number 3

      hi, i complete the whole game already. im trying to complete this trophy but i cant no longer visit abstergo again… any idea of how can i revisit again or do i have to start a new game to do it?

        Go to the pause menu, then Exit. It will give you 2 options

        1) Exit from the Animus
        2) Exit to the main menu.

      Went thru all your guides for the sphere puzzle ones but they do not solve the sphere puzzle for the room on the right at the entrance of the building on the lobby floor. Room requires level 3 access. Any help would be lovely since I cannot for the life of me solve this one.

          You will get level 3 access as you progress through the story You can’t the area till you have the access.

          I am not sure about the puzzles though. One speculation might be that they are somewhat random and there is no way to pinpoint the sphere puzzles except for rewards you get at the end.

          We will also be uploading a video soon so that things become easier.

        They are marked on your map. Do you have the level 3 security access? Have you hacked all the servers too?
