Just extend Array with the functions

class Array
 def row i
   at i-1
 end

 ...
end

gm = GridMaster.new
gm.create_grid
gm.grid.row(1)

though I'm quite shure that this design is not very good. Maybe for a
start put create_grid into the initialize method

class GridMaster
  def initialize
    self.create_grid
  end
end

gm = GridMaster.new
gm.grid.row(1)

but I don't know what you want to achieve, so take this hint just as
an uninformed hint
