Alot of people play the lottery on a regular basis and give little thought to how they select their numbers. This will not tell you how to predict all the winning lottery numbers but it will help you to choose your numbers more wisely, so that you turn the odds more in your favour. The advice is based on analysis of winnning Lottery numbers all over the world, going back in excess of 15 years, it looks at patterns most often seen in the winning lines, I tested alot of the advice by analysing the past winning lottery numbers, and yes alot of what has been said is true. I think one of the best pieces of advice given was only play what you can afford to, or feel comfortable with, and rather than play 5 lines every game it is much better not to play each game save the money and wait until you are able to play more lines in one game, your odds improve when you play 50 lines as opposed to 5. I would say it is better for a regular lottery player to buy this book, because if they are playing and not winning anything year in year out, this may help them understand why and maybe get them more frequent wins of 3 and maybe 4 number prizes (based on UK lotto). THIS IS NOT A BOOK THAT WILL ENABLE YOU TO PREDICT NUMBERS SO YOU CAN HIT THE LOTTERY JACKPOT, it can however change the way you play to increase your odds of winning. Ultimately Lottery is a gamble, even if you use all the advise she gives in this book you can play and still not win. I hope this helps and clears up what this book can and cannot do.
