Crypt Puzzle (Maze)


Hint 1 of 16:
There's really no way to give a straight solution to this puzzle, since
the initial conditions are randomly generated.

Hint 2 of 16:
I found that it was best to work on one coffin or group of coffins at a time
at the start of the puzzle, until I reached some kind of recognizable pattern
or order to the state of the lids.  Trial and error is the only real
strategy here, at least when you're starting out.

Hint 3 of 16:
But if the above technique doesn't work for you, there is a definite
solution that will get you to the end.  I should warn you first that the
solution I'm about to give is probably the *least* efficient.  The only
advantage it has is that it's guaranteed to work.  I recommend you try to
get to the end and turn only to these hints when you're hopelessly stuck.

Hint 4 of 16:
I've numbered the squares in this puzzle a bit differently from the systems
used in other solutions.  The top row is numbered 1-3, left to right, the
middle row is 4-6, and the bottom row is 7-9.
