This book is very technical but offers no specific playing strategies.
First, the author divides the wheel into 6 sections ("global pie" chuncks.) Then, he illustrates various patterns on the betting layout to help visually memorize where numbers and sections are on the wheel (not necessary because you can look at your own notes when you're at the roulette table.) Then, he reverse-engineers the numbers on the wheel to show various mathematical relationships between numbers in their arrangement on the wheel. If this is not useless information, then the author fails to convey what value there is to it (all I could keep thinking, as I read and re-read this part of the book, was... "SO WHAT??") Then, he presents another set of sections called "Global Stars", which are non-connected, symetrically opposed numbers on the wheel (rather than blocks of numbers like the "pies.") Finally, he concludes that when a single Global Pie merges with a single Global Star, the exact number is predicted. Yes, obviously, if you can predict the right star in the right pie chunk, you get the right number, but he doesn't tell you how to DO that.
The jist of his methodology seems to be that by observing where the ball is landing (into which global pies and stars), one can predict where the ball will fall next, by tracking the "ball movement." The movement of the ball is analyzed by observing if the ball is doing a "hemi", a "bow-tie", or a "nuke", which refer to the ball landing in pie sections that are adjacent to each other, or opposite each other, or somewhere in between.
The author gives no examples of how a playing session might go. There are no example sets of spins, showing what you would bet on next and why, nor will you find any explanation of what exactly constitutes a trend, and how you should bet on it. If there is any value to this book, it will be up to the reader to extract it and work out his own system for utilizing the information presented.
