Should tren have a rule that every block contains a number? If not I don't see how the example's solution is unique


This is right, thank you. I'll amend the last line to 'Each block must contain exactly one number'.

Location: United States		For Arrow Flow, is it possible that some collection of arrows forms a cycle? Or must every arrow eventually lead to a number?

Fair point. Every arrow must lead to a number. I'll amend this in the next version.
