The Pi-e Piper of Hamming
(Published on 21. November 2020, 14:26 by steelwool)
The Pi-e Piper is a wizard mathematician, living in the small town of Hamming (where error correcting digits abound).
When he charms the children, he always take a route forming one of his magic numbers, either Pi or e.
That is 3.14159265359 and 2.71828, if you didn't know.
One route goes through Red Square, the other through Green Park. A route is always a sequence of orthogonal squares. The two routes never touch, even diagonally or to themselves.
All Killer cages have sums under 10, with no repeating digits.

I added a couple of digits to the cages. Originally I believed just having cages present would be enough to force a solution path, but some numbers are needed to force uniqueness. Sorry if anyone had problems with this as a result, but thanks to the person who informed me about the issue.
