Discussion of the rules for the "only XL-4" tournament.

The question is, what skill is involved in navigating here???

Well, you seem to understand:p
Although a lot depends on the density and size of the zones, and if you add one or two templates, it becomes more difficult.

Part 2: ... The generator has a tendency to throw in some particularly bizarre templates.

There won't be any of those. Only from the existing five + possibly some playable but unused one.
