Level One
Began at random. Chose point 7 steps away. Went right. Got point 6 steps away. Repeated. Got point five steps away. Repeated. Got point 4 steps away. Skipped 4 squares right. Got point 6 steps away. Returned to previous point and went right. Got point 3 steps away. Repeated. Got point 4 steps away. Went 3 squares down from previous point. Got point 6 steps away. Went 3 squares up from “3 steps away” point. Found treasure.
Level Two

Skipped three squares down. Got point 6 steps away. Went three squares up from previous point. Got point 4 steps away. Returned to “three steps away” point and went up. Got point 2 steps away. Skipped 2 squares left. Found treasure.
Level Three

Got point 9 steps away. Returned to previous point and skipped 5 squares down, outside purple band. Found treasure.
Level Four
Began at random. Chose point 10 steps away. Went up the Y axis. Got point 9 steps away. Went up the Y axis. Got point 8 steps away. Skipped 2 marks up the Y axis. Got point 8 steps away. Went one mark down the Y axis. Got point 7 steps away. Went up the Z axis. Got point 6 steps away. Skipped 4 marks up the Z axis. Got point 2 steps away. Went down the Z axis. Got point 3 steps away. Returned to previous mark and went up. Got point 3 steps away. Returned to “2 steps away” mark and went right. Found treasure.
My Strategy
I begin randomly upon the graph, then progress in each direction of the compass separately. Once I find one that minimizes the number of steps to the treasure, I continue until the number begins to increase. When that happens, I retrace my steps to the coordinate of the lowest step number and then once more progress in each direction of the compass separately. Once I find the right direction, I continue upon it till I find the treasure.
I tried my best, but I know that this strategy leaves much to be desired, and believe that I will improve upon it in the future.
