Subject: Matrix type ?

Hello ruby fellows,

Maybe you can help me.

I'm currently trying to make a Sudoku solver for my first ruby program.
Sudoku is a nice 9x9 board game with simple rules, but it can be tough
to solve. More infos at http://www.sudoku.com/ if you want to launch a
RubyQuizz :-P

What I would do, is use a kind of 2D Matrix that would represent the
board but couldn't find a satisfying method.

This is my current implementation using arrays : 
----
board = Array.new
      
(1..9).each do |row_num|
  board[row_num] = Array.new
  (1..9).each do |col_num|
    board[row_num][col_num] = "X"
  end
end
----
If I "puts board", I'd like to have a 2D view instead.
How does puts work, does it call the to_str method ?

Also, I'd like to access the console as a 2D Array too,
so that I can write on screen directly like a text-framebuffer.

I have so many questions.. :-)
/me is refraining to flood ruby-talk
