0%B5%D1%82 In the same place: Regional singularities of "Schastlivost" of the ticket can be defined several methods. The greatest propagation was received by three of them: Moscow - if on the bus ticket the six-place number is printed, and the total of first three digits is equal to the total last three this ticket is considered happy. Leningrad, or Petersburg (less widespread) - if the total of the digits standing on even places of the ticket, is equal to the total of the digits standing on odd places of the ticket the ticket is considered happy (in St.-Petersburg, on the contrary, this method name "Moscow"). Other variant - the totals of each pair digits are equal. Affirms also that a method of count of the totals of the first and second triples of numbers Muscovites name "Moscow", and - "Leningrad", and both those, and others attribute a method of count of the totals on even and odd positions to other city.
