==Overview==
'''Binary Homeworlds''', designed byis [[Andrew Looney]],'s isname for athe two-player variant of the game [[Homeworlds]], designed by [[John Cooper]].
The popularity of Homeworlds is attested by its featuring in several of Looney Labs' packagings of the pyramids
and multiple online implementations.
 
==Materials==
Line 41 ⟶ 47:
|{{PL|::SSS|blue|4em}}

4536 pyramids in four colors (3 trios in each color) are needed to play.
 
==Goal==
Line 83 ⟶ 89:
Since binary star systems often contain two different sizes, they can be even more limited in what they connect to.
 
Ships will always be right next to these star systems, never off on their own on the table. Any size and color of ship may belong to either player. So how can we tell whose ships are whose? Orientation. If a ship is pointing away from you, it's your ship. If a ship is pointing at you, it's your opponent's.
==Homeworlds Technology==
Both stars and ships in Homeworlds possess different kinds of technology depending on their colors.

Stars in Homeworlds grant their visitors the usage of different kinds of technology depending on their colors. Ships do the same for their owners. The actions are explained in detail in the [[#Actions|Actions]] section. If you own a ship in one of these colors, or if your ship is visiting a star system of these colors, you can perform the associated actions at its location. This is important to keep in mind, because you are about to create a star system and a ship.
 
If you own a ship in one of these colors, or if your ship is visiting a star system of these colors, you can perform the associated actions. This is important to keep in mind, because you are about to a star system and a ship.
 
==Setup==
#Place a bank of 4536 pyramids off to the side in 1512 neat stacks, one for each size and color of pyramid.
#Flip a coin.
#The winner builds a binary star system out of any two sizes and colors she wishes using pieces supplied from the bank of 4536 pyramids off to the side. She places this on the table in front of her. This binary star system is her '''Homeworld''', and to stay in the game she must always keep at least one of her ships at it.
#She then selects any large pyramid from the bank and places it on its side as a ship, next to the newly-formed star system. The ship will be facing away from her to indicate ownership.
#Her opponent now does the same.<br>
:The layout on the table will eventually look something like this:
#The same person who won the coin toss and set up her binary system first now takes the fist move.
 
{|class="wikitable" style="width:55%; margin:auto;"
|Player 1 (south) has chosen a binary homeworld made up of a medium green and a small blue.
Player 2 (north) has chosen a binary homeworld made up of a large yellow and a small green.
The single pyramids standing up in between the two players represent the star systems that will be discovered during the course of the game. (No ships are shown in this example.)

#The same person who<br>Whoever won the coin toss and set up her binary system first now takes the fistfirst move.
 
==Actions==
On their turns, players select a star system and perform one action in that system. The actions available for a player to take depend on the colors of pyramids in the star system where the action is taking place. The power to do these actions can come from the color of the player's own ships or from the color of the stars that make up the star system that ship is in.

*'''Movement''' Take one of the ships you have in any existing star system and move that ship to a new system. The destination system must be connected to the star system the ship began in. So if the beginning star system consists of {{PL|::SL|grey|3em}}, then the ship can only connect to a star system made of a medium pyramid {{PL|::M|grey|3em}}. The player does not have to limit himself to star systems that already exist on the table: he can send his ship out to ''Discover'' a new medium star system by taking a medium-size pyramid of any color from the bank and placing it on the table, then placing his ship next to it.

*'''Movement''' Take one of the ships you have in any existing star system and move that ship to a new system. The destination system must be connected to the star system the ship began in. So if the beginning star system consists of {{PL|::SL|grey|3em}}, then the ship can only connect to a star system made of a medium pyramid {{PL|::M|grey|3em}}. The traveling player does not have to limit himself to visiting star systems that already exist on the table: he can send his ship out to ''Discover'' a new medium star system by taking a medium-size pyramid of any color from the bank and placing it on the table, then placing his ship next to it.
 
*'''Trade''' Change the color of your ship. Take one of your ships and return it to the bank of pyramids not in play. Then replace a pyramid of the same size from the bank, but a different color.
Line 138 ⟶ 180:
<br>During an attack, ships are never removed from the board or returned to the bank. They just change ownership.
 
*'''Sacrifice''' YouInstead of taking your one free action, you may sacrifice one of your ships during your turn by returning it to the bank. This will let you perform 1-3 actions associated with the color of the sacrificed ship, one action for each pip the ship had. You are not limited to performing the actionresulting actions in any particular star system; the actionsthey can be performed in any star systems where you have a presence.
 
==Catastrophe==
==Galactic topology==
When a star system contains four or more pyramids of the same color, it becomes '''Overpopulated''' and unstable. Either player can then declare a catastrophe and return all pieces of that color from the star system to the bank. If the star itself gets returned to the bank as a result of this, then ships of all colors that were at that star system get returned to the bank, as well. Players are not required to declare the catastrophe.
The topology of a Binary Homeworlds game is simpler than the [[Homeworlds_strategy#Galactic_Topography:_The_Shape_of_the_Game|topology of a multi-player game]], because there are at most two binary stars. If the two players choose homeworlds of different sizes, then the galaxy can be laid out in rows between the two players so that movement "toward" and "away from" a homeworld maps directly onto movement across the table.
 
==Rules Clarifications==
[[Image:BinaryHomeworlds-topology1.png|thumb|right| The most common topology]]
* You can't attack another player if the only source of red technology at that star system is ''your opponent's ship''. The tech must come from the star itself or from your own ship.
[[Image:BinaryHomeworlds-topology2.png|thumb|right| A less common topology puts the homeworlds nearer each other]]
* Sacrificing a piece counts is done ''instead'' of taking a free basic action. So you cannot move to a new star system and then sacrifice a large yellow ship at that star system in order to get four movement actions in a row. The maximum number of any action you can take on a turn is three, and only by sacrificing a large.
* A catastrophe can occur at a player's homeworld star system, and can result in the player's binary star turning into a single star system. That star system still functions as the player's homeworld, and that player is still alive and in the game as long as there are ships at his once-great system.
* Players are allowed to try to engineer catastrophes at each other's homeworlds.
* Players are not allowed to deliberately throw the game by destroying their own Homeworlds.
 
==Trivia==
[[Image:BinaryHomeworlds-topology2.png|thumb|left| A less common topology puts the homeworlds nearer each other]] Binary Homeworlds differs from the original multi-player Homeworlds in that it discards the [[Werewolf]] aspect; the game is simply a fight to the death between two players. The topology of a Binary Homeworlds game is simpler than the [[Homeworlds_strategy#Galactic_Topography:_The_Shape_of_the_Game|topology of a multi-player game]], because there are at most two binary stars. If the two players choose homeworlds of different sizes, then the galaxy can be laid out in rows between the two players so that movement "toward" and "away from" a homeworld maps directly onto movement across the table.
