Irony Kukuba | product class

Numbers are present on card in 2 formats. One as classic format and other one as distributed format between 1-30, 31-60, 61-90.
Numbers in 2nd format i.e. distributed are present/or has to be written in such a way that they are not same to any of the numbers present in classic format ticket.

Irony here is that when hosts call a number and if it is not present in classic format then it might be present in distributed format. Chances of winning are more.
