I'd say that was a bit strong. It also looks contradictory ie how can you be intellectually challenged when something is very difficult to solve? Perhaps a better wording is required. Anyway, I have seen people post to this forum saying that the challenge with multiple solution puzzles is finding all of the different solutions.
It's not
my cup of tea, after all you could just put in any old number and the chances are that the puzzle will work out which renders the solving process completely redundant and thus doing the puzzle a complete waste of time. But that's only my POV. Never having (knowingly) done a puzzle with more than one solution I can't really say. Perhaps there are advanced solving techniques for these puzzles that we don't know about, since the majority here don't do them.
