Well, some lottery players would consider my question a bit unusual but I don't mind. Many people avoid numbers related to birthdays for example, because if they win it means sharing a JP with many others. Honestly, I do not even think about JP. By my opinion, it is a bit too hard to be the luckiest one in a country in a specified flash or moment. Therefore, I play lottery for fun and if I hit occasionally (once in a month or two, for example) five out of six I would be quite satisfied. So my question: is there any known strategy that works somewhere between good and well for a five out of six, even if it excludes the chances for a JP?
