What is "Hackers of Catron"?
o Electronic Settlers of Catan® board. Settlers of Catan is a
resource gathering and trading board game in which
players compete to build the largest economy.
What we will improve upon?
o The game is really fun, but it takes too long to set up. We
will shorten the setup process.
o Make resource gathering and spending automatic.
o This project intends to simplify the execution of Catan
without adding more complexity.
