Use the singleton method. A few years ago, a statistician discovered a statistical quirk in the production of scratch-off tickets, which can double your chances of winning if exploited correctly.[1] Basically, scratch off games operate under the assumption of "randomness," but can't be produced in a truly random way, because the lottery board needs to keep track of how many winning tickets are in circulation.

Find the expected value. This is a good idea for any lottery game you are considering playing.

The only responsible way to play the lottery is to do so occasionally for fun, without any expectation of winning. When it turns into something else, you know it’s time to stop.
