Hi, I need help on how to interpret the lotto tickets. When I buy them (usually 10,000 dong) the packs the ladies have have several tickets of the same number (5 digits) ? also there is a smaller number like for eg A7 or B6 above the 5 digit lotto number. when I log onto the website to check the results I notice that there is an additional right hand side column with several numbers less than 10 in it ? also I'm wondering for the number one "special" prize of 250,000,000 dong how can their be one winner if several tickets have the same number ?
