This book will challenge seasoned KenKen players, enhance their solving techniques, and provide hours of fun puzzle play and brain training.
NEW RULES ARE INTRODUCED ...

• Limited-operations puzzles, where puzzles may contain only addition, only subtraction, or a mix of addition and subtraction.
• No-operations puzzles, where puzzles will use all four operations including multiplication and division, but YOU have to figure out which operations to use.

... AND A BRAND NEW PUZZLE
Twist puzzles where instead of using 1 to 6 for a 6 x 6 puzzle as you do in regular KenKen, you'll use a different candidate set each time. In one puzzle, you might use {1, 2, 3, 7, 8, 9}; in another, you might use {2, 4, 6, 7, 8, 9}. Different combinations will present exciting new challenges.
No puzzle involves guesswork ... there is always a logical way in!
This collection of 6 x 6 puzzles is perfect for any experienced KenKen player ... from beginner to expert!
Hours of Fun, Challenges and ultimate Satisfaction!!
KenKen is an exciting, mind-expanding puzzle based on "The Art of Teaching without Teaching", an ingenious teaching philosophy developed by KenKen's creator and renowned educator, Tetsuya Miyamoto.
