The communist state of Arstotzka has just ended a 6-year war with
neighboring Kolechia and reclaimed its rightful half of the border town,
Grestin. Your job as immigration inspector
is to control the flow of people entering the Arstotzkan side of Grestin
from Kolechia. Among the throngs of immigrants and visitors looking for
work are hidden smugglers, spies, and terrorists. Using only the
documents provided by travelers and the Ministry of Admission’s
primitive inspect, search, and fingerprint systems you must decide who
can enter Arstotzka and who will be turned away or arrested.
