# A Lifetime's Supply of Cryptarithms!

### Introduction to a Lifetime's Supply of Cryptarithms

Thank you for choosing a Lifetime's Supply of Cryptarithms, and welcome! This site has over 4 million cryptarithm puzzles. If you solve one a day, you'll finish them off in about 11000 years. Hopefully by then I'll have added another 4 million! 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 site, the following rules apply -

• Each letter corresponds to a different digit
• There are no leading zeroes

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

• You know M is not 0, since there are no leading zeroes. So you figure out it must be 1.
• Then, you know E is not 1, since each letter corresponds to a different digit. In fact, none of E, I, S and A are 1.

Then, you continue solving the puzzle!

### Using the Site

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 'SNOW'. 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, SNAPS-SPACED. Follow that link, and scroll down to the word SNOW. Following that link leads to links to the 3321 puzzles containing SNOW, organized into 4 pages. Explore this list to find a nice puzzle containing 'SNOW', 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!
