In 2005 I turned the grand old age of 40, so here
is a maze to mark the passing of the years. Starting from the
central square, step out the roman number sequence from I to
XL (1 to 40), starting I, II, III, IV etc. The roman-numeral
sequence doesn't stop at 40 however, so as a secondary challenge
why not see how much further you can go... 50? 60? 70? Email
me, if you think you find the true upper limit.
No doubt some people will use software to solve this maze,
especially the second challenge (no brownie points for this,
it isn't very tricky at all). So for these people I reserve a
special third challenge... is it possible to construct a maze,
on the same 7x7 grid, where the sequence can run even deeper?
I used software to help develop this maze, but I can't (yet)
claim it's optimum. So if you find you can improve on it, please
let me know.
Update April 2007: In September
2006 Ben Small cracked my final challenge and found a maze grid
that runs deeper than my original maze. Ben used software again,
but again cannot be sure his grid is optimum. So now I can relaunch
the second and third challenges afresh! Email me if you find
the upper limit of Ben's challenge and definitely let
me know if you can do any better.

Step out the roman numeral sequence from I to XL (1 to 40) using
grey squares to punctuate the sequence. So that's I,II,III,IV,V
etc using a grey square to mark each comma. Hint: keep an eye
on the rolling ticker-tape underneath the grid if you can't remember
how to count in roman numerals.
Use Restart (Action), or hit space, to reset the
Hit 'u' to unwind the move-sequence to last grey-square
(can be repeated to unwind as far as desired).
Use the cursor keys to move. At each move you can
step to any adjacent square (left, right, up, down). Note, the
same letter can be used many times, even within the same numeric.
