Welcome To Mr. Logic's "4-Digit Puzzles!"

(This game is for Windows computers only)


This game consists of a series of levels, each of which contains a different "secret rule" by which a given 4-digit number changes into another 4-digit number. As a clue to help you guess what the secret rule is, you will be shown an example of how one particular 4-digit number changes.

For example, in the screenshot shown below, you are given the clue that the number 2850 changes into 2851.

In this case, a reasonable hypothesis might be that the rule is simply: "Add one to the given number". Therefore your response to the number 1026 (in the second line) would be:

1027

If your guess is correct, you will be asked to apply the same rule to yet another  4-digit number (in order to confirm that you really have discovered the actual rule and that your first response wasn't merely a lucky coincidence). In this "confirmation test", both the red and blue frames in the image will each change to green so as to alert you to the fact that a correct answer will now advance you to the next level.

If you get stuck at some point and can't figure out the rule that the current level is using, don't be afraid to just guess. There's no penalty for wrong answers. (In fact, some levels actually expect you to make several wrong guesses before you can gain enough information to correctly deduce the rule that is being used.)

Use the keyboard to enter your responses (followed by the "Enter" key). The "Backspace" key clears your response. The "Esc" key exits the game. (Before exiting, you will be asked if you want to save your current level. If you respond with "Yes", you will automatically return to your current level the next time you restart the game.)

The object of the game is to try and reach level 21. If you get there, you will be given a secret password. If you are one of the first ten players to email that password to Mr. Logic, your name will be added to the game's Top Ten List.

Mr. Logic's "4-Digit Puzzles"  game can be played either in full-screen mode, or in a window. Just download and unzip the corresponding "4-digit"  folder:

"Mr. Logic" is the producer of many online puzzle games. In the Spring of 2002, he created the concept of the "Online Riddle" when he released his Cybertrek adventure game. Since then, hundreds of other game makers have implemented his "URL-completion" method in the design of their own games (e.g., "This Is Not Pr0n", etc.).

Secret Coded Messages

(For Windows Computers Only)

             

Want to have fun creating your own secret coded messages?   Just download our SiMPLE encrypter/decrypter program (called "Secret") and save it onto your desktop.   (No installation
is required.)   Then drop any text file onto "Secret".   It will automatically encrypt the message contained in that file.   [The name of the file containing the encrypted message will begin with
a plus ( + ) sign.]

To decrypt  the message, just drop the file containing the encrypted message back onto "Secret".   The decrypted message will then be returned to you in a file that has the same name that the encrypted file had, but without the plus ( + ) sign.

(Tell all your friends to download their own copy of "Secret",
and then have fun exchanging secret messages with them!)



Secret Joke #12

Instructions for Decrypting the Secret Joke:

Copy and paste the entire encrypted joke into a new text document whose name
begins with a plus sign followed by one or more letters (e.g., "+joke.txt").
Then drop that text document onto your copy of "Secret".
