I think this is a little cleaner:

make_board returns a board split by spaces.

i.e. you enter the rows like

1 0 1 0 2 1 8 2 1
1 2 1 1 9 1 9 1 9
...

The method returns the actual array, and I map and join for pretty
printing in the puts.
Tweak as needed, code below.
------------------------------------------------

def make_board
  board = []
  puts "input rows, seperated by spaces:"
  9.times { board << gets.split(" ")[0..8].map { |e| e.to_i } }
  return board
end

puts make_board.map { |r| r.join(" ") }.join("\n")
