The article first briefly review the origin and development of the lottery, sums up the previous literature, think the lottery is random lottery and is predictable; Then, through the analysis of the mechanics of the SSC of the ratio of betting amount to award setting and the winning probability, combined with the trend and probability theory, this paper proposes a lottery number prediction method; Finally, as for the proposed prediction method with practice, using the method of historical data test and practical test, the effectiveness of the methods made records and statistics, prove the feasibility of lottery prediction and the prediction method is effective.
