Cryptarithms are sometimes called crypt-arithmetic puzzles (from the words cryptic and arithmetic), or alphametics (from alphabet and arithmetic) or letter arithmetic or verbal arithmetic. When I decided to make a cryptarithms game for this website, I wrote a computer program to generate them. To my surprise, it started producing millions and millions of puzzles - far too many for this website!
I've picked out a few of the best ones put them here, but if you want more, I've put the other millions and millions on a separate website - Cryptarithmania.
In the meantime, scroll down to enjoy the ones I've picked out here!
Remember that for each puzzle, these rules apply :
- Each letter corresponds to a unique digit from 0 to 9 - different letters correspond to different digits.
- No number in the sum has a leading 0.
- Each puzzle has a single unique solution
First of all, here's a gadget that gives you a new Cryptarithm puzzle every day. You can add this gadget to your iGoogle home page, or to any web page :
If you really get math into your heart, it's like a poem or a beautiful song...
Sometimes, to get good at math, you just need to practice and practice until it becomes a habit...
... and finally, when you become mighty at math, you'll find it a lot less stressful!
Here's a few tougher puzzles, involving much bigger numbers. This first one reminds me of the story of Mary Poppins...
Perhaps a person who fixes bedding material?
Life is full of surprises - as this puzzle explains, it's likely that we will enjoy multiple surprises...
Well, that's all for now. Remember to visit the site where I've put the rest of the cryptarithms I found!
