:description=For an extra challenge why not try adding more rows or columns?

This is the same level with an extra row.
For comparison clicking after a random time in the original wins once every 40 games, and with the extra row it wins once every 420 games. We could even "improve" the starting positions of the rabbots to help avoid exhaustive search.
When a level gets like this, does it even count as fun any more? It was fun to create...
