What is smart banko?

Unfortunately, as an AI language model, I do not have access to information about specific products or services related to financial institutions unless it has been made publicly available. However, the term "smart banko" seems to refer to a type of lottery game similar to bingo that is popular in the Philippines. It combines elements of chance and strategy, and the objective is to guess the correct combinations of numbers. The game is often played in community gatherings, and participants can win cash prizes.
