not having much luck with this puzzle. the puzzle is you have to forge your own visa ID number and deduce how the numbers are generated so the forgery doesn't get flagged as fake.so far I only figured out the last two are the city code, so "08" is the number distinguishing the city of origin (Gujas). The game does have a hint button I suppose, and in-game hint buttons don't count as cheating but I haven't used it yet.
