在Ruby上非常新,并尝试将数组与嵌套数组进行比较

所以我正在构建一个tic tac toe游戏,我试图从我的板哈希中拉出键,然后将其与数组中的数组进行比较.问题在于获胜的组合都有3个值,但是可能需要玩家4或5次获胜,所以我想看看这些4或5值是否包含其中一个获胜组合(希望这是有意义的).具体问题是使用winner_check方法,有没有办法让这个方法有效？

def initialize_board
  board = {}
  (1..9).each {|position| board[position] = ' ' }
  board
end

def empty_positions(board)
  board.keys.select {|position| board[position] != 'X' && 'O'}
end

def player_turn(board)
  puts "Let's play Tic Tac Toe! Pick a position 1-9 and try to beat me."
  position = gets.chomp.to_i
  board[position] = 'X'
end

def computer_turn(board)
  position = empty_positions(board).sample
  board[position] = 'O'
end

def winner_check(board)
  winning_combos = [[1,2,3],[4,5,6],[7,8,9],[1,4,7],[2,8],[3,6,7]]
    winning_combos.each {|combo|}
      if board.select { |k,v| v == 'X' }.keys.include?(combo)
        puts "You've won! Great job!"
      if board.select { |k,v| v == 'O' }.keys.include?(combo)
        puts "Looks like the computer outsmarted you,try again!"
      elsif
        puts "Looks like you've tied,try again!"
      end
    nil
  nil
end

def game_over?(board)
  empty_positions(board) == []
end

def draw_board(board)
  puts
  puts " #{board[1]} | #{board[2]} | #{board[3]} "
  puts "---+---+---"
  puts " #{board[4]} | #{board[5]} | #{board[6]} "
  puts "---+---+---"
  puts " #{board[7]} | #{board[8]} | #{board[9]} "
  puts
end

board = initialize_board
draw_board(board)

until winner_check(board) || game_over?(board)
  player_turn(board)
  draw_board(board)
  winner_check(board)
  computer_turn(board)
  draw_board(board)
  winner_check(board)
end

winning_combos.each {|combo|}
  if board.select { |k,v| v == 'X' }.keys.include?(combo)
    puts "You've won! Great job!"
  if board.select { |k,v| v == 'O' }.keys.include?(combo)
    puts "Looks like the computer outsmarted you,try again!"
  elsif
    puts "Looks like you've tied,try again!"
  end
nil

winning_combos.each { |combo|

  if board.select { |k,v| v == 'X' }.keys.include?(combo)
    puts "You've won! Great job!"
  elsif board.select { |k,try again!"
  end
}
