Your if was nested funny, this should do what you want, I think:

class Jogo

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

       def joga(usuario)

               result =3D sorteia()
               resultSorteio =3D result.to_i

               puts(resultSorteio)
               puts (('11' * 2).to_i/2)
               if resultSorteio =3D=3D 1 then
                   maquina =3D "pedra"
               elsif resultSorteio =3D=3D 2 then
                   maquina =3D "papel"
               else
                maquina =3D "tesoura"
               end

               puts(maquina)
               puts(usuario)
               usuario.chop
               if usuario =3D=3D maquina then
                       puts("empatou")
               else
                       puts("alguem ganhou")
               end

       end
end

j =3D Jogo.new()

print "Digite pedra, papel ou tesoura: "
opcaoUsuario =3D gets()

j.joga(opcaoUsuario)
