- e-mail ENTROPY -- FAQ
-
- Q: What is e-mail Entropy?
- A: e-mail Entropy is a board game of abstract strategy.
-
- Q: What are the rules of Entropy?
- A: The board has 25 squares, or spaces, arranged in a 5 x 5 grid,
- as shown below.
-
- S S S S S <---5
-
- S . . . S <---4
-
- . . . . . <---3
-
- O . . . O <---2
-
- O O O O O <---1

- Fig. 1 Starting Position
-
- In this diagram, S and O represent two sets of pieces; seven to
- each player. The dots are empty squares.
-
- THE OBJECTIVE is to disperse your pieces so that each one
- is placed next to a piece of the other color only, not their own.
-
- MOVES
- 1. A piece can move only if it is next (incl. diagonally) to another
- of the same color. Such a piece may be moved any number of empty
- squares, in a straight line, and in any one direction. BUT,...
-
- 2. If, in your turn to move, you have a piece that is next to
- neither one of its own, nor one of the other color, then you are
- in check, and your only move is to clear the check. If it can't
- be done, you must pass.
-
- EXAMPLES:

-
- Fig 2. The O side is in check Fig. 3. What's O's best move?
-
-
- In Fig.2, the O side is in check, since the piece at c5 is isolated.
- (One possible way out is for O to play a4-c4, clearing the check
- and creating one for S at the same time.)
-
- Fig.3 shows S threatening to win with d2-e1. (O can preempt this
- with b2-b4, which denies the piece at c2 its connection.)
-
- Q: How do I start a game?
- A: By convention, the O's play first. The easiest way to start a
- gane is to just copy Fig.1 into your editor and proceed from there.
- (By sending away your first move.)
-
-
- Q: What is the most powerful tactical weapon of Entropy?
- A: Without doubt, the check. Often, by skilfully checking your
- opponent you can effectively freeze him or her long enough for you
- to find a winning combination, as in the following example:
-
- S . O S O
-
- O . . . S
-
- O . . . O
-
- . O . . S
-
- S S S . O
-
-
- In this position O is to play and win. Can you find the winning
- move?
-
- Q: Can I put myself in check?
- A: "In check", as described in rule 2., applies only when you
- take your turn. So you can put yourself in check in one
- turn, and then clear out of it in the next.
-
-
- Q: Can I be in multiple check?
- A: Yes. And if you are in a multiple check (i.e., you have more
- than one isolated piece) your only legal move is one that removes
- all the isolations simultaneously.
-
- Q: What happens if both players arrive to a winning position at
- the same time?
- A: If you succeed in dispersing your pieces as required,
- but your last move puts your opponent in a winning position
- as well, the game is considered a draw.
- For example,in the following position O is in check and at S's
- mercy.
- S O S O S
-
- . S . . .

- O . O . O

-
- However, if after 1. pass, S plays: 1..., b4-b3; 2. pass, c2-e2
- both players would have achieved the game's objective simultaneously,
- and it's a draw.
- To win, S must first create a second isolation, thus 1. pass, b4-c4;
- 2. pass, c2-d2; 3. pass, d2-e1; 4. pass, c4-d3. This maneuvre leaves
- O with an isolated piece at a3.
-
- Q: Is a forced draw possible?
- A: Yes. For instance, in the next position S can't move again,
- but O cannot win either, since all squares surrounding the piece
- at c3 are off-limits. (An O on any of them is a win for S!)

-
- Q: Is there a table-top version of Entropy?
- A: Yes. A commercial version is being readied.
-
- Q: How long does it take to play an average game?
- A: Ten to fifteen minutes.
-
- Q: Is Entropy suitable for children?
- A: Entropy is especially suitable for children, because, among
- other things, it is devoid of grown-up references like,"war",
- "king", "castle", "territory", "variation", "seki", "ko", and
- so on.
- It is a game that seeks to instill the elementary and civilized
- logic of accomodation rather than the primitiveness of annihilation.
-
- Q: Is Entropy strictly for two players?
- A: No, it isn't. In the "bridge" mode four people can play in a
- two-against-two format. Each pair shares the same pieces, and
- partners sit facing one another as in bridge. Of course, you
- need the table-top version for that.
