Pay no attention to the picture on the right. Its very easy once you get the hang of it. Each segment is split into 8 columns going from top to bottom and each segment has 8 options starting from the first piece of the fingerprint then moving over one to the right on each segment.
Here is a example The first piece of the fingerprint which is column 1 we can call " number 1 " this is segment 1. Then the next column which we move to we will start on the first piece of the fingerprint then scroll once to the right for " number 2 " this is also segment 2. Keep doing this until the hack is complete.
