solution for level 4
First, guess anywhere. then find all of the possible places it could be, being the number of steps away. e.g. if it said it was 2 steps away from 6,4,5 then I would find all the places 2 steps away from 6,4,5. use maths on a sheet of paper and addition + subtraction rather than trying to imagine it on the graph. Treat it like a set of numbers instead. e.g. 6,5,6 is 2 steps away from 6,4,5 because I added 1 to the 4 and 5. Then try one of the places it could be. e.g. 6,5,6 is 4 steps away. Then find all the possible places for that. Only use the ones that match up. e.g. 6,2,3 is 2 steps away from 6,4,5 and 4 steps away from 6,5,6. then try one of the matches. Then use what you got to get even less possible places until you know where it is.
da da da! you found where it is on level 4. this method also works for the level 1.
