TRAIN YOUR BRAIN TO SEE THE POSSIBILITIES. The puzzles in the book are challenging, but each one can be solved without guessing or using candidate placeholders. Throw away the eraser, only write down a final answer, and have fun while you improve your skills. Each puzzle has a suggested order of moves, complete with an explanation for each answer. If you choose to solve it in a different order, a glance at the completed puzzle can help you through any rough spots. Patricia O'Connor has spent years developing and teaching adult education courses, and this book is one more way in which she can share what she has learned. The proposed method of solving the puzzles significantly improved her skills and enjoyment, and it can help you, too.
