I think the text is useful for describing the ultimate goal, but agree that visual suggestions would make it easier to figure out what the problem is about.

For example, I read this as a variation of the knight's tour but was confused as to why they didn't highlight the visited squares. (Answer: it isn't a knight's tour since each square will be visited more than once.)

Another example, the description itself didn't quite make sense since it mentioned a sequence but didn't really say that certain squares must be skipped. (In retrospect, the answer is obvious. The queen makes certain squares invalid destinations, along with being invalid intermediate steps to that destination. But it won't be obvious to some people upon initially reading the instructions.)

Finally, the purpose of the square shown in the completion gauge isn't explained at all. Since it is not explained, I did not link it to the description of the goal.
