Honestly, the challenging part is figuring out what the goal point is.Ya these types of puzzles work best imo when a large group work together on them. That way each person only needs to try out a couple ideas and progress is much nicer to luck into.
I came up with two puzzles based off the one. The only difference is for one puzzle I'd change one of the digits and the other has one less digit.
But the same picture otherwise is the puzzle.
Same set up, wildly different ways about going out about it.
These puzzles are like blindly trying to find something in a room full of toys. You know when you don't have anything, but you are never really sure if you are close to picking up the right toy, or even if you are looking for a toy at all.
What close solutions did you find? The actual one is pretty stupid but statistically I wouldn't think other probable answers exist.
