There is no straight answer to this question. It actually depends on what you are looking for and what makes a good lottery game for you. If you fancy a game with the best odds of winning, you should go for the Saturday Lotto, Monday Lotto, and Wednesday Lotto games. If you want a huge jackpot game, then you should opt for the Oz Lotto. For an excellent all-around lottery game, you should choose the Australian Powerball.
