I think that secret_room(818) == 4 is an incorrect test. Before eight hundred eighteen there are eight, eighteen, eight hundred and eight hundred eight. Then I changed spelling of eighteen to eightteen and passed. If that misspelling is really used in tests it should be changed.

The question is resolved.
