An easier puzzle combining arrow and mod-3 set logic. For reference, the mod-3 sets are:
- 1, 4, and 7.

- Be from a single mod-3 set (eg: 9=6+3).
- Be arranged such that in every 3 digits along the arrow and its attached circle there is one digit from each of the mod-3 sets (eg: 6=1+2+3).
You must determine which arrow is which in order to complete the puzzle.
