"Introduction:"

//1.67vx
1.1. |2co {
@B{Spaceships} is a zero-sum game for two players, which can
be played either as a single "game[2]" or a series of games
making up a scored "match[9]" or continued
"match[10]." 
}
//1.67vx
1.2. |2co {
It is played in two @B{spaces}, one for each
player.  
}
//1.33vx
1.2.1. |2co {
Each space is a 3-dimensional 5x5x5 grid of
cubical @B{cells} of
which 
}
//1.33vx
1.2.2. |2co {
only the identity and relationship between the cells "(not" the
size, exact shape, orientation or "handedness)" is
relevant. 
}
//1.33vx
1.2.3. |2co {
Cells are @B{adjacent} if they share a
"face;" 
}
//1.33vx
1.2.4. |2co {
cells are @B{loosely adjacent} if they share any face, edge
or
vertex. 
}
//1.33vx
1.2.5. |2co {
A set of several cells is said to be "adjacent[1.2.3]" or
loosely "adjacent[1.2.4]" if each cell in the set is adjacent
or loosely adjacent "(respectively)" to at least one other cell
in the
set. 
}
//1.33vx
1.2.6. |2co {
The spaces do not
"`wrap'." 
}
//1.67vx
1.3. |2co {
The object of the game is to cause all of your "opponent's"
"ships[3]" to be "destroyed[3.10]" before they destroy
yours. 
}
//1.67vx
1.4. |2co {
Spaceships is not a game of perfect information.  Players
record their play privately, revealing only certain information
to each other,
and 
}
//1.33vx
1.4.1. |2co {
reveal their records of their play for checking by the
other player after each "game[2]" is
finished. 
}
//1.33vx
1.4.2. |2co {
Mutually trusting players need not reveal their records of
the game to each
other. 
}
//2.00vx
@CNP
@B{2.} |2co {
A @B{game} consists of the following
"phases:" 
}
//1.67vx
2.1. |2co {
@B{Setup}":" each player secretly "records[11.3]" the locations and
"identities[3.3]" of their "ships[3]." "[11.6],"
"[11.6.1]" 
}
//1.67vx
2.2. |2co {
Thereafter play proceeds in @B{turns}.  During each
"turn:" 
}
//1.33vx
2.2.1. |2co {
the two players first secretly "record[11.5]" their "actions[4]"
for that turn and the effects of those "actions;" when both
players have done
so 
}
//1.33vx
2.2.2. |2co {
each reveals the visible "aspects[5]" of these actions to the
other. 
}
//1.33vx
2.2.3. |2co {
Each player secretly records the effects of these visible
aspects, and makes known their @B{visible
results}. 
}
//1.33vx
2.2.4. |2co {
Finally "(or" earlier "[11.7.3])," each player reports to the
other the types, locations and identities of any of their
ships which will be "destroyed[3.10]" at the end of the turn,
and flashcube "data[7]" is
exchanged. 
}
//1.33vx
2.2.5. |2co {
There is a conventional "notation[11]" which includes a
conventional coordinate "system[11.4]," and a conventional interaction
"ordering[11.7]" for the "players'" reports to each
other. 
}
//1.33vx
2.2.6. |2co {
The actions, their availability, their effects and visible
aspects, and the possible effects and visible results are
defined in "[4]" and
"[5]."

2.3. |2co {
@B{Termination}":" 
}
//1.33vx
2.3.1. |2co {
If at the end of a "turn[2.2]" either player has no
"ships[3]" which are not "destroyed[3.10]" the game terminates
immediately. 
}
//1.33vx
2.3.2. |2co {
If at the start of a "turn[2.2]" either player has no
possible "actions[4]" other than kamikaze "strikes[4.5]" and
"scans[8.3.3]," and during that turn that player does not record
any actions other than scans, then the game terminates at
the end of the
turn. 
}
//1.33vx
2.3.3. |2co {
A "player's" @B{score} in a game is the amount of remaining
"materiel[2.3.5]" they have when the game
terminates. 
}
//1.33vx
2.3.4. |2co {
The winner of a game is the player with the higher "score;"
if both players have the same score then the game is a
draw.

2.3.5. |2co {
A "player's" @B{remaining materiel} is the number of
"undamaged[3.8]" cells in their
"ships[3]."
