Subject: My application doesn't work well

Hi everybody,

My application isn't working well. Let me try to explain what's wrong.
When I run my program appears something like:

ruby pedrapapeltesoura.rb
Digite pedra, papel ou tesoura: pedra
1
tesoura
pedra
alguem ganhou

This 1 that appears above is the value of resultSorteio variable, the
content of this variable come from a method which random a number
between 1 to 3. tesoura is the value of the variable maquina, however if
the variable resultSorteio is 1 the variable maquina should be pedra and
not be tesoura, and sometimes the variable is empty...if you try to play
many times you can see where is the word tesoura above will appears
nothing. Does somebody help me please. Here is my code:

class Jogo

        def sorteia
                opcoes = ['pedra','papel','tesoura']
                numero = 1 + rand(3)
                return numero
        end

        def joga(usuario)

                result = sorteia()
                resultSorteio = result.to_i

                puts(resultSorteio)
                puts (('11' * 2).to_i/2)
                if resultSorteio == 1 then
                        maquina = "pedra"
                        if resultSorteio == 2 then
                                maquina = "papel"
                        else
                                maquina = "tesoura"
                        end

                end

                puts(maquina)
                puts(usuario)
                usuario.chop
                if usuario == maquina then
                        puts("empatou")
                else
                        puts("alguem ganhou")
                end

        end
end

j = Jogo.new()

print "Digite pedra, papel ou tesoura: "
opcaoUsuario = gets()

j.joga(opcaoUsuario)
