    Looks interesting but a wall of text and too much difficulty understanding the problem means I'm skipping it.

    I want to do this Kata but I can't tell what problem is being described. Can someone further clarify the rules?

      You can perform an operation on the board: add or subtract 1 from two adjacent values. So for example:

      1,1,1,1
2,2,2,2
3,3,3,3
4,4,4,4

      You can transform it to something like

      1,1,1,1
2,3,3,2
3,3,3,3
4,4,4,4

      or

      1,1,1,1
2,2,1,2
3,3,2,3
4,4,4,4

      And you can do this as many times as you want.

      board1 and board2 are the initial and final state of the board but there is an unknown value in board2, your task is to find this value ;-)
