- I don't have VTC privilege on this site yet, but, if I did, I would be inclined to leave It is related to a type of mathematics gameIt is related to a type of mathematics game closed because it is a mathematics problem and not a mathematics puzzle. A question shouldn't be reopened just because the original close reason has been resolved; it should be reopened only if it is worthy to be open.
- Maybe this is an incorrect way of thinking, but: The question appears to have a unique solution (answer), and it has gotten that answer (twice). It's not clear what purpose is served by opening the question to new answers.
