I've gotten 4 out of 5 playing Fantasy Five on two occasions but that is only $200+ compared to 5 out of 5 which could be $50,000 or more. Once I had to stop playing because of lack of income and my lucky numbers got the 4 out of 5 again. Arrrrgggh!
The only proven strategy is to play the same numbers over and over again. Even then the odds are a gazillion to one.
