I am trying to make an Arrows puzzle, but I don't know if there are multiple solutions.
For those who don't know, an Arrows puzzle starts with a grid of numbers (example from SE) surrounded by empty boxes.
The goal is to put an arrow into each outer box such that the number in each square in the grid matches the number of arrows pointing at it. Arrows must either be pointed directly at the grid or at a 45 degree diagonal.
The solution for that puzzle is therefore (credit to Sconibulus for the solve):
The question then is can an Arrows puzzle have multiple solutions?
