- Introduction
- ------------
-
- Lobster is a program which allows you to play scrabble against your Mac.
-
- The recommended system for this game is any colour Mac running System 7.x with
- a 14" monitor.
-
-
-
-
- How to play
- -----------
-
- Simply follow the prompts on the screen. Either you or Newton (your computer
- opponent) can start the game.
-
- When faced with the 'Enter your word' prompt, you have a number of options:
-
-
- a) Type in a word to play (in lowercase). A blank tile is denoted by an
- asterisk. To play the blank, type in the required letter in UPPERCASE.
- For example, if you have a rack containing 're*olts' and you want to
- use the blank as a 'b' to play the word 'lobster', type
-
-
- Enter your word
-
- ==> loBster
-
-
- and press RETURN.
-
- You now need to type in details about where to play the word. To play
- your word starting with the first letter at row 'h' and column 'f' and
- playing ACROSS the board, type
-
-
- Enter play details
-
- ==> hfa
-
-
- To play down the board, use the letter 'd' instead of 'a'. Lobster will,
- of course, check for illegally placed words.
-
- You can press ESCAPE at any point to restart the entire procedure.
-
- Once you've typed in your word and play details, Lobster will score it for
- you and ask if you want to commit yourself to that play. If not, you can
- type in another word. If you do, then Lobster will look up your word in
- its lexicon and challenge it if necessary. You can tell Lobster to accept
- the word but if you abide by its decision, you forfeit the move.
-
-
- b) Exchange part or all of your rack by typing SWAP. Then key in the letters
- you want to exchange. If you type SWAP and change your mind, just hit the
- ESCAPE key.
-
-
- c) You may pass by typing PASS. If both players pass twice in consecutive turns,
- the game ends.
-
-
- d) When your brain is numb and you can't play on, you can ask Leibnitz, another
- computer player, to take over for you. Just type COMP. If you type COMPX, you
- will not have to press the SPACE BAR after each move.
-
- To continue the game yourself, press the ESCAPE key just after Newton has
- played and keep it pressed until play is returned to you.
-
-
-
-
- Saving games
- ------------
-
- You can only save and load games when it's your turn to play. You can also save
- finished games to review at a later date, particularly useful if you've just
- won.

- Technical Details
- -----------------
-
- Lobster has a 29,000 word lexicon which happens to contain all valid 2, 3 and 4
- letter words (in accordance with the English OSL, 1991). It will therefore play
- some very obscure words; this is not for the faint-hearted. Most words tend to be
- Americanised, e.g. 'harbor' is in the lexicon, 'harbour' isn't.
-
- The computer algorithm is based on a powerful technique proposed by Appel and
- Jacobsen (CACM, May 1988, Vol.31, Number 5, pp.572-8). This method allows Lobster
- to compute ALL possible legal moves given a board position, a rack of letters and
- a lexicon. As a result, it plays a formidable game.
-
- Lobster averages well over 350 points per game. However, Lobster has no positional
- sense and will leave triple word squares open for the opponent. It doesn't try
- to keep a 'well balanced' rack either; instead it aims to beat you by sheer, brute
- CPU force with an unfaltering eye which doesn't miss a thing.
-
- If the computer takes a while to make its move, then it's very likely holding a
- blank in its rack.
-
- This software was produced using Think Pascal 4.0. The author wishes to remain
- anonymous.
