1) To start, select "conventional game", then enter the number of digits you want to guess.
The computer will then select a random number, based on the number of digits you chose.
In the conventional game, the computer number includes any of the digits zero through nine no matter how many digits you choose to guess. For example, if you choose 3 digits, the number could be 257 or 981 or 203, etc.
This computer-generated number will have NO repeated digits and will NEVER begin with a zero.


2) Similarly, when you enter guesses, repeated digits and leading zeroes are NOT permitted.


3) Enter your guess, then press "Tab" on your keyboard.



4) The output boxes will then show you:
Guess # (How many guesses you have made)
Your Guess (The number you just entered).
Digits (The number of digits in your guess that match the computer-generated number.) (Example, if the computer number is 921 and your guess is 123, then this box would say '2'.)
Order (The digits in your guess that are in the same POSITION as the computer-generated number.) (Example, if the computer number is 921 and your guess is 123, then this box would say '1'.


5) By using these clues, you can logically deduce the value of all the digits.


6) When you have guessed the computer number, you are DIGITALLY CORRECT and can click the "New Game" button for another try.


7) If for some reason, you want to quit in the middle of a game but still need to know the number, just scroll ALL the way to the bottom and click DAS QUITTEN SWITCHEN which will display the number.


D E R A N G E D   G A M E   I N S T R U C T I O N S


In this version of the game, the computer-generated number has NO repeated digits and NEVER contains a zero (unless your choice is 10 digits).
The lowest digit is always 1 (except for 10 digits) and the highest digit is the number of digits selected.
For example, if you chose 3 digits, the largest digit will be 3, and the chosen number can only be:
      123   132   213   231   312   321


1) To start, select "deranged game", then enter the number of digits you want to guess.

2) Enter your guess, then press "Tab" on your keyboard.

3) When you enter guesses, repeated digits and any zeroes are NOT permitted.

4) Unlike the conventional game, the deranged version requires a completely different strategy because every one of your guesses will always match all of the digits.
The best (and maybe the only) strategy is to find numbers that match absolutely none of the digit positions in the computer number. (numbers that equal zero in the order column).
Such numbers are called derangemets and now you know why we gave this game its "deranged" name.
Let's suppose you have chosen 3 digits and your first two guesses are
      2 1 3 and
      3 2 1
both of which score a 'zero' in the order column.
We then can conclude that only '1' can be the first number, only '3' can be the second number and only '2' can be the last number.

To see even more about derangements, go to this page and read Puzzle 26.

As with the conventional game, if you want to resign the game but still want to know the number, scroll down to "Das Quitten Switchen".

NOTE: This game is based upon 'BAGELS' a computer game from about 25 years ago but this version is 100% the work of 1728 Software Systems.
Going further back than that, this game used to be played with paper and pencil. It is a good test of logic and deductive reasoning.
Yes, hard as it is to believe, there really were games before the Nintendo Wii, the Sony PlayStation 3, the XBox 360 or even Sudoku made their appearances.
Why not give this a try?


This is actually an improved version of the old 'BAGELS' game because:
1) 'BAGELS' generated only 4 digit numbers.
2) The answers to each guess were in weird terms like PICO PICO FERMI. We at 1728 like to speak plain English.
3) 'BAGELS' only permitted a fixed number of guesses (15 or20 ). With DIGITALLY CORRECT, you can keep guessing until doomsday because we have set NO LIMITS on the number of guesses you are allowed.
4) 'BAGELS' did not have 'DAS QUITTEN SWITCHEN'.
So there.

















Gave up huh? Well then...........
