KenKen was invented by a Japanese math teacher who said he believes in “the art of teaching without teaching.” That goes right along with our philosophy of playing your way to a healthier brain so, naturally, we were instant fans of these fun and addictive puzzles. The Little Gift Book of KenKen boasts 250 puzzles with instructions and an introduction by New York Times Crossword puzzlemaster Will Shortz. Likened to Sudoku with basic math, KenKen will help you brush up on your math skills and give your brain a workout.

How to Play: For a 3x3 puzzle, you will only use the numbers 1,2,& 3. For a 4x4 puzzle, you will only use the numbers 1,2,3,&4. etc. Each puzzle will either use one type of mathematical operator or a combination (addition, subtraction, multiplication, division). The darkened boxes are called cages. There is a target number inside each cage. Use the numbers available and the mathematical operators indicated to reach the target number. Numbers cannot be repeated in a column or a row. If a target number is in a caged box by itself, that is the answer for that square. How to Win: If you successfully use every number available without repeating a number in a column or row, the puzzle is solved (check your answer in the back of the book!).
