An interesting little book (which fits in pockets) that informs readers about lottery theory, and how it all works. The mechanics of lottery systems are explained which are useful basics in learning to unravel how best to play to try to win prizes, or if you are very lucky, a jackpot. The book is aptly short and to the point so that readers are not bombarded with too much complicated information. Some playing strategies can be learned from the book which can be used in practice for a variety of Lottery games. Don't expect to go out and win the lottery every time after reading it, because as the book explains, there is more to lotteries than that. You will however, be able to make more informed playing choices that will give you an edge over other players. Overall an enjoyable and informative read which should be stimulating to those with enquiring minds.
