T-Zero map mystery solved

[marnanel]

I've found the problem with the T-Zero topiary map. The exits from each room depend on the direction you entered from. So rather than 25 rooms, it makes more sense to talk about 100 (5 rows by 5 columns by 4 directions).

I've run a bot over the maze with this assumption and this is a rough diagram of what I've found.


Red = prohibited by rules
Blue = permitted
Green = prohibited by hedge (boundary or middle)
Grey = U-turn; universally prohibited
Black = special

There are two special points: the one at (0,1) leaves through the entrance, and the one at (4,3) leaves through the exit and wins.

Heaven help anyone trying to map this with pen and paper.
