- SHAREWARE VERSION
-
- WHAT IS CRYPTO?
- ---------------
- CRYPTO is a Windows version of the popular Cryptogram puzzles often found
- in puzzle books or the Sunday paper. CRYPTO will exercise your brain: you
- will use your intuition and imagination while learning a little about the
- English language, and you will read a lot of interesting, thought-provoking,
- and sometimes downright funny quotes of famous, not-so-famous, and wishing-
- they-hadn't-been-quoted people.
-
- REGISTERING CRYPTO
- ------------------
- CRYPTO is copyrighted software. It is not in the public domain, nor is it
- distributed for free. The author retains all rights to this software.
-
- CRYPTO is distributed as Shareware so you can try it out without risk to
- see if you like it. Use it for two weeks. If you don't like it, simply
- delete it and owe nothing. If you continue to use CRYPTO after the two
- week trial period, you must register your copy. To do this, send US$10 to
- the author:
-
- Kenneth A. Reek
- 3090 Griffin Rd
- Churchville, NY USA 14428-9512
-
- For your convenience, the file REGISTER.TXT is included: it contains a
- registration form that you may use.
-
- CompuServe users may also register the program by typing GO SWREG and
- selecting registration ID #2317.
-
- Registered users of CRYPTO will receive and be automatically registered
- for the next major revision of the program free of charge. Features being
- considered for the next version include scoring for multiple players, and a
- memory to prevent selection of quotes you've already solved. Registered
- users may also call or write for information on the latest revision, to
- report bugs, and make suggestions or other comments about CRYPTO. I am
- particularly interested in your ideas for making CRYPTO a better game.
-
- DISCLAIMER
- ----------
- CRYPTO is supplied as is. The author disclaims any and all warranties,
- expressed or implied, including but not limited to warranties of merchant-
- ability and of fitness for any purpose. The author assumes no liabilities
- for any damages, direct or consequential, which may result from the use
- of CRYPTO. (For heaven's sake, it's only a game!)
-
- INSTALLING CRYPTO
- -----------------
- Installation is easy. First, you must unpack the archive file containing
- the distribution (if you're reading this, you have done that already). You
- should have the following files:
-
- crypto.exe executable Windows program
- crypto.qot quote/phrase file
- crypto.txt the file you are reading now
- register.txt registration form
- bwcc.dll Borland C++ support routines
-
- Copy the files "crypto.exe" and "crypto.qot" to any directory you wish;
- they must reside in the same directory. Bwcc.dll may be put in this same
- directory or the windows\system directory. To start CRYPTO, open the File
- Manager, display the directory containing "crypto.exe". Now double-click
- your mouse on "crypto.exe", or use File|Run and enter the command "crypto".
-
- Should you decide to register CRYPTO, you may wish to add it to one of the
- groups in the Program Manager. Here is how that is done:
-
- 1) Open the group to which you have chosen to add CRYPTO.
- 2) Select File|New from the Program Manager.
- 3) Verify that the box which appears says "New Program Item", and
- click OK.
- 4) Enter the following values:
- Description: CRYPTO!
- Command Line: crypto.exe
- Working Directory: (the directory where you put crypto.exe
- and crypto.qot)
- 5) Click the OK button.
-
- Now CRYPTO can be started merely by double-clicking its icon in the group
- to which you added it.
-
- HOW TO PLAY THE GAME
- --------------------
- The following sections describe what cryptograms are, how the game is
- played, and how you go about finding the solution for a cryptogram puzzle.
-
- WHAT IS A CRYPTOGRAM?
- ---------------------
- A cryptogram is an ordinary phrase or quote. What makes it interesting is
- that it has been disguised by changing its letters. For example, all of the
- A's may have been changed to Q's, all of the B's to W's, etc. Text that has
- been disguised in this manner is called "ciphertext." The original text of
- the phrase is called "plaintext."
-
- OBJECT OF THE GAME
- ------------------
- A cryptogram is solved by guessing which plaintext character each cipher-
- text character stands for. When you have gotten them all, you will see
- the original phrase.
-
- PLAYING THE CRYPTO GAME
- -----------------------
- When CRYPTO is running the screen is divided into two windows. The left
- window contains the ciphertext; this is shown in red.** The right window
- shows two things: first is a list of the plaintext letters that have not yet
- been chosen, shown in blue. The right window also shows the number of
- times each ciphertext character appears.
-
- ** Note: these are the default colors. You can change to other colors if
- you prefer. See below for details.
-
- To make a guess, point to a ciphertext (red) character with the mouse and
- click the left mouse button. (You can point to a ciphertext character in
- either window.) The character you have chosen will turn black everywhere it
- appears in the phrase. Now point to the plaintext (blue) character you
- think it stands for and click the left mouse button again. This plaintext
- character is now shown over every occurrance of the ciphertext character in
- the cryptogram. If you wish, you can select the plaintext character first,
- then the ciphertext character.
-
- As you guess more and more plaintext characters, you should begin to be able
- to read the quote; if what you see doesn't make any sense, then you may have
- made some wrong guesses. If you wish to undo a guess, simply point the mouse
- at the ciphertext or plaintext character you wish to undo and click the
- right mouse button. Also, if you have selected the wrong plaintext
- character (or the wrong ciphertext character, if you select that one first),
- clicking the right mouse button will erase it.
-
- If you can't get started, try getting a hint from the Hint menu. Hint|Big
- tells you the plaintext letter for the most often used ciphertext char-
- acter. The next big hint exposes the next most often used ciphertext, and
- so on. Little hints expose the least often used ciphertext. At any time
- during the game, Hint|Confirm can be used to verify whether or not your
- guesses so far are correct. Hint|Undo Error will identify and undo one
- incorrect guess, or tell you if there are none. Finally, Hint|Solve Puzzle
- does just that.
-
- STRATEGY
- --------
- The letter frequencies are one key to solving cryptograms. While different
- authorities will list them in slightly different orders, the most commonly
- used letters in ordinary English text are E, T, O, A, N, I, R, S, and H.
- It is likely, then, that the ciphertext letters which appear most often
- stand for these letters, but there is no guarantee: try them in various
- orders and see what you get.
-
- Letter frequencies are not the only thing, however: you can also look at
- the ciphertext for clues. For example, there are only two English words
- that are one letter long, "a" and "I." If you see a one letter word in the
- ciphertext, it must be one of these. If it is not capitalized, it must be
- an "a." Contractions, three letter words which appear over and over (e.g.
- "the", "and") and punctuation also provide clues. But watch out for
- abbreviations and other unusual text.
-
- After selecting a plaintext letter, look throughout the phrase and see if it
- makes sense everywhere it appears. For example, if you find that your
- selection has created a two-letter word in which both letters are vowels,
- something is obviously wrong.
-
- WINNING
- -------
- For all practical purposes, the game is over when you can read the quote or
- phrase. Technically, though, you haven't won until you finish it on the
- screen, so CRYPTO won't admit that you have won until you actually mark all
- of the plaintext characters correctly. In fact, placing the last letters
- on the screen will sometimes show that the quote was not quite what you
- thought it was.
-
- Casual or beginning users will use hints to solve the cryptogram. Purists
- will refuse to use any of the hints, and will consider a game lost if they
- have to undo any guesses. You should play CRYPTO in whatever manner you
- enjoy the most.
-
- CHANGING SCREEN COLORS
- ----------------------
- To customize the colors to your liking, choose the Game|Change Colors
- menu entry. You will be shown a menu of six different things whose colors
- can be changed. Select one of them and click OK, then select the desired
- color. Note that only solid colors (not the dithered representations) may
- be chosen; for reference, the "Custom Colors" section shows all the valid
- solid colors. Then click OK. The menu of things to change will reappear;
- you can select another one, or click CANCEL when you are satisfied with
- the colors. Your colors will be saved and continue to be used when you
- run CRYPTO in the future.
-
-
- Thank you for trying out CRYPTO, and I hope you enjoy it. Remember to
- register the program if you wish to use it past the trial period!
