Имаш значителни проблеми със спазването на конвенциите на места, направи справка с ръководството за стил.

  • %w{:spades :heart :diamonds :clubs} == [":spades", ":heart", ":diamonds", ":clubs"], което пък е различно от [:spades, :heart, :diamonds, :clubs]
  • методите help и before_help са лошо именувани
  • array е лошо име на променлива
  • праен списък се създава с [], а не с Array.new

и т.н.
