Issue 2 contains 118 Tri-Alphametic Puzzles.

The objective is to decode the numeric phrase and discover the hidden word. Each letter in the three equations can be exchanged for a number (e.g., all A's might be 7, and all T's might be 0).

You must figure out the number that is associated with each letter, so that the equations add up correctly. There is only one solution.

Once you have done this, you are able to convert the string of numbers into letters to decode the phrase. Finally, using your knowledge of the phrase, select three words, one from each equation, and add them together to reveal the hidden word.

As these puzzles are based on addition, they are suitable for students and adults of all ages. Of all the puzzles presented on this USB, Tri-Alphametics are the most applicable to classroom use. They promote problem solving skills and logical inference. As these puzzles are based on logic they do not alienate the less able students and in some cases these students are able to solve them faster than more rational or formal approaches made by more able students.
