Binary Homeworlds help needed!
I run an after school game club for the students at my high school. My intention is to teach them to play Binary Homeworlds after school today. In preparation I took home my copy of Threehouse and Playing With Pyramids last night and refreshed myself on the rules. Then I promptly left the books sitting on my desk at home.
So, I need someone to correct me on any mistakes I might be making in these general rules as well as remind me what the colors signify.
Green � Grow
Red � Attack
Yellow � Move
Blue � Trade?
Black � not used?
I know each player makes a binary star at the beginning with 2 large pieces as their home system. Players can only move ships to star systems that do not share a piece size as the system a ship is leaving. You get one action a turn unless you cash in a ship for actions equal to number of pip counts.
I specifically forget what causes an overpopulation. How many of one color in a star system causes this?
Note: I was taught the game at Origins 2008 and haven't had the opportunity to play since. :(
