 Playground Maze (Posted on 2009-08-13)
 A B C D E F G H I J K L M N O P Q R S

In this maze the exits/entrances are the triple coloured bars, green, yellow and magenta. Your path is defined by the sequence of those colours; ie, if you start at the top you may only enter a cell in the order of the cyclic sequence of G-Y-M (or the reverse order if you begin from below).

The object is to complete this maze, visiting each cell at least once. While there is more than one route, the shortest routes are 31 and 34 letters. What are those routes?

Looking at the entrance into B, I see stacked together green, yellow and magenta in that order before entering into B from the outside. As brianjn calls it, it's a triple coloured bar, as is the exit, which starts with a green and ends with a magenta.

If one were, however to treat the entrance as solely green, then the following would work:

with, as before, the numbers representing the actual rooms on the list. Each of these also requires allowing more than one passage through a given portal in the same direction.

The only change to the program was the initial placement in the color sequence:

roomList\$ = "B": currSeq = 2
