```ruby
class GamesController < ApplicationController
  def index
  end

  def create
    game = Game.create

    redirect_to game
  end

  def show
    @game = Game.find(params[:id])

    @game.deal
  end
end
```

user
```ruby
class GamesController < ApplicationController
  def index
  end

  def create
    game = Game.create!

    redirect_to game
  end

  def show
