  The Internet has become a critical domain for modern society that requires
ongoing efforts for its improvement and protection. Network traffic matrices
are a powerful tool for understanding and analyzing networks and are broadly
taught in online graph theory educational resources. Network traffic matrix
concepts are rarely available in online computer network and cybersecurity
educational resources. To fill this gap, an interactive game environment has
been developed to teach the foundations of traffic matrices to the computer
networking community. The game environment provides a convenient, broadly
accessible, delivery mechanism that enables making material available rapidly
to a wide audience. The core architecture of the game is a facility to add new
network traffic matrix training modules via an easily editable JSON file. Using
this facility an initial set of modules were rapidly created covering: basic
traffic matrices, traffic patterns, security/defense/deterrence, a notional
cyber attack, a distributed denial-of-service (DDoS) attack, and a variety of
graph theory concepts. The game environment enables delivery in a wide range of
contexts to enable rapid feedback and improvement. The game can be used as a
core unit as part of a formal course or as a simple interactive introduction in
a presentation.
