1 star for concept, 0 stars for functionality

I liked the idea, but quickly realized that it never rewrites the numbers when no matches remain, so it is unwinnable to start with.
The other problem is it wont remove valid pairs that wrap around lines, as it describes in its own tutorial.

If it is fixed, Id try it again, but as it stands, I will not play it any more.
