A custom-labeled grid is provided for every puzzle, like the one you see to the right. The grid allows you to cross-reference every possible option in every category. You can eliminate pairs you know aren't true with an X, and pencil in pairs you know are related with an O. If you know, for example, that Lauren wasn't born in 1961, you can add an X in the box where the Lauren column and 1961 row meet. Similarly, if you know that Bryant was born in 1971, you can add an O in the appropriate box. Furthermore, since every option can only be used once in any given puzzle, you can eliminate the four other options for Bryant in that category (1937, 1946, 1961, 1975) and the four other options for 1971 (Anahi, Jayden, Lauren and Nikolas). I always do the logic puzzles first so a magazine full of them is perfect for me! I like the way they link together so you use the answers from one to complete the next one. I enjoyed the Tessellation puzzles and would like more of these.

In each puzzle you are given a series of categories, and an equal number of options within each category. Each option is used once and only once. Your goal is to figure out which options are linked together based on a series of given clues. Each puzzle has only one unique solution, and each can be solved using simple logical processes (i.e. educated guesses are not required). The puzzles are written in a light-hearted style, with regular characters and story settings. Every solution gives a step-by-step explanation of how it is derived. Continue doing this for every clue you're given. Eventually you will have filled in enough X's and O's on the board that you will then be able to use simple logic to deduce the solution to the puzzle. For example, if A = B, and B = C, then A must equal C. Similarly, if A = B, and B =/= D, then A must not equal D.
