You will look at an incomplete word, and your brain will go to work recognizing patterns, and you will solve each problem.In every puzzle in this book, you will be given a fragment of a word, and will be required to guess the complete word. Hints and answers are both provided, in case you're stuck. Happy solving!Direct correlation with IQ increase and cognitive abilityWord games of the type featured in this book are directly related to your ability to solve problems that are simple on the surface but complex underneath, almost exactly like an iceberg. If you want to measure this directly, you can stare at one of these word puzzles for a while, and measure the time you need till you guess the answer correctly (without using hints). If you do this twenty times in a row with twenty different puzzles, and measure the time taken to solve each, you will notice a clear downward trend in the times - this proves that, even over the course of a casual half hour "playthrough" of the word games in this book, there is a clear and measurable improvement in your ability to solve simple or complex lexical problems, and the effect will be much more pronounced as you spend more and more time with all the puzzles in this volume, and in this series.All the benefits of a physical workout, but for your mindAfter a good long workout at the gym, you feel good.

So, whether you're looking at interesting letter sequence patterns in the first 5 letters of a word that you have to guess, and ignoring the last few letters temporarily, or filling in placeholder letters in position 2 and 4 (the crucial letters to fill), you will have your hands full with coming up with unique solutions in real time to difficult questions.
