Thank you for choosing a Lifetime's Supply of Cryptarithms, and welcome! This CD has over 4 million cryptarithm puzzles. If you solve one a day, you'll finish them off in about 11000 years. Hopefully by then we'll have another CD ready. This is, truly, a lifetime's supply of cryptarithms!
Cryptarithms are sometimes called cryptarithmetics, alphametics or letter or verbal arithmetic. Whatever you call them, they're the same fun, challenging puzzles!
For the puzzles on this CD, the following rules apply -
So, suppose you grew up by the ocean, and every time you see it, you are reminded of all your old friends. Then, you might try to solve the puzzle SEE + SEA = MISS. Then
Then, you continue solving the puzzle!
If you're just itching to solve some puzzles, first think of a word you'd like to see in the puzzle. Suppose you chose 'OX'. Then, click on 'Word Lists' in the menu - this leads to a list of links to lists of words. Scroll down until you find the link to the list containing your word - in this case, ME-SIXTY. Follow that link, and scroll down to the word OX. Following that link leads to links to the 3 puzzles containing OX in this preview. (The full CD has 8631 more, organized into 9 pages.) Explore this list to find a nice puzzle containing 'OX', and try to solve it!
Along the way, you'll
see links to lists of other words. One of these might catch your eye.
Explore away, and solve whichever ones you like. You have a lifetime's
supply of cryptarithms now!
The other menu items are explained below...
The CD needs a browser with javascript enabled. For the best experience, make sure the latest java plugin is installed too. For more information, see the Technical Requirements section just below, or read the Help section. Java is needed to see the solutions to the puzzles. If we had tried to fit 4 million puzzles and their solutions onto the CD, we would have had to use a DVD instead! So, we built a simple Cryptarithm Solver and put it on each puzzle page. It can't solve all possible cryptarithms, but it can do the ones now in your hands. On any of the puzzle pages, click 'Show Solution', give the Solver time to work, and hey presto, the solution will appear. Of course, I know you won't cheat! Not too often, at least...
The puzzles on this CD are organized as a bunch of web pages. This means the CD should work under any modern operating system, using the web browser of your choice. We tested it under a variety of popular combinations, and it worked fine.
The CD needs javascript to be enabled in order to run. We also recommend that you have the latest java plugin installed in your browser. You can test these requirements here.
The rules for cryptarithm puzzles are simple. Each letter represents one of the digits 0 to 9. Different letters represent different digits. The first digit in a number can't be 0. Your job is to find out what digit each letter represents. This CD has all the cryptarithms you'll ever need...
