This free online fun game develop the perceptions of the words for speed reading and
slowly reading. This game is a Flash version of the cryptogram puzzles. Break the
code and reveal the message. Crypto-gram selects a sentence from the list. Then
it crypts it, and presents it for solving. This crypto gram game challenge the mind.
The object of it is to solve the puzzles by selecting letters and placing them onto
the crypto grams map. You can add your own words or sentence into the list. Also
you can print the puzzle and present it for your school friend or send flash program
by e-mail. This program is absolutely free. Fun for all ages and skill levels.

What is the Cryptography
There are two kinds of cryptosystems: symmetric and asymmetric. Symmetric cryptosystems
use the same key (the secret key) to encrypt and decrypt a message, and asymmetric
cryptosystems use one key (the public key) to encrypt a message and a different
key (the private key) to decrypt it. Asymmetric cryptosystems are also called public
Symmetric cryptosystems have a problem: how do you transport the secret key from
the sender to the recipient securely and in a tamperproof fashion? If you could
send the secret key securely, then, in theory, you wouldn't need the symmetric cryptosystem
in the first place -- because you would simply use that secure channel to send your
message. Frequently, trusted couriers are used as a solution to this problem. Another,
more efficient and reliable solution is a public key cryptosystem, such as RSA,
which is used in the popular security tool PGP.
How to solve a cryptogram
See if you can recognize some of the partially solved words. Let's say there
is a DIS4. That might be either DISH or DISK. Now take a look at other words. If
you find one where substituting 4 with either an H or a K makes any sense, then
that's probably it.
Take a look at the hint if one is provided. Hint is a word or words that are
written in plain letters. If you can guess a word next to the hint, you will have
cracked those numbers. For example, if there is CHEWING 123, you might guess that
123 is GUM. Sometimes the hint word is repeated somewhere in the cryptogram. See
if you can find a word with the same pattern of characters as in the hint.
Short words can sometimes be guessed, because there are not too many possibilities.
Here are some common short words:
one letter: a, i, (o)
two letters: of, to, in, is, it, be, as, at, an, by, he, on, or, so, if,
three letters: the, and, for, are, but, not, you, all
You can use a frequency analysis technique. The "E" letter is the most common
letter in the English language. If you count the numbers and find that The letter
"$" is the most frequent one, then "$" maybe is a "E". You can then do the same
with other letters. However, since the secret messages are not very long, this method
may be inaccurate, and you will have to try other letters of similar frequency as
well. Complete order of letter frequencies is: E T A O N I R S H D L U C M W F Y
P G B V K J X Q Z.
