When calculating the final number only count each number the first time it is touched no matter how many times after it gets touched.
(Ie. if the solve zig zags back over a 1 multiple times its just one 1. That does not mean that a 1 later on in the maze shouldn't be counted.)
Each number is counted that the line even slightly touches.
If done correctly you will end up with a very long string of numbers to enter into Certitude
Safety warning: There is often a lot of sharks in the water in this area.
