I think it's because when you write `puts board[rcount]', `rcount' is 1 
higher than the highest index number in board. Try this instead.

   def make_board
     puts "Push enter, then begin input. (For Input Format Compliance, 
extra enter key is necessary)"
     gets
     board = [[],[],[],[],[],[],[],[],[]]
     9.times do |i|
       # you may want to use gets.chomp instead
       instr = gets
       board[i] =
[instr[0].to_i,instr[1].to_i,instr[2].to_i,instr[3].to_i,instr[4].to_i,instr[5].to_i,instr[6].to_i,instr[7].to_i,instr[8].to_i]
       puts board[i] # the last item in `board'
     end
     return board
   end
