Here is an interaction in a tic-tac-toe game, with user input in bold: >> gm = Game.new(\'andy\', \'mike\') => # >> gm.play_game(\'mike\') Mike, enter your next O move (1-9): 1 O-- --- --- Andy, enter your next X move (1-9): 3 O-X --- --- Mike, enter your next O move (1-9): 5 O-X -O- --- Andy, enter your next X move (1-9): 3 Bad move dude! You go again. O-X -O- --- Andy, enter your next X move (1-9): 6 O-X - OX --- Mike, enter your next O move (1-9): 9 O-X - OX --O Mike, you won! => nil >> gm.play_game(\'karen\') I don\'t know that player. Please try again. => nil >> gm.play_game(\'andy\') Andy, enter your next O move (1-9): 5 --- -O- --- Implement this output using Ruby
