C++ Game Project Due In 3 Days With Flowchart

You are to create a project that implements your favorite board or card game.  It has to be a game that is well known and has been around for more than 10 years having well documented rules that you can look up online.  No, Tic,Tac,Toe is not complicated enough and that is not a board game or card game.  This is worth 20% of your grade equivalent to all the homework you have done so far.  It is to be comprehensive and only utilizes the concepts up to structures.  You will get to use classes on the follow up project to this.
