MyPlusLotto gives you a chance to play up to 50 weeks in advance. Since I do this regularly, I would recommend you to try it. Since you would only need to hand in your lines once in a year, there would not be any risk of forgetting. You can easily have one line at least on every week of the year.

You have a choice of playing one line or even several lines up to 50 weeks in advance even as you choose between 1 and 50 as your week. You can now time your lotto games with your tax returns or other specific times of the year. If you are short of money then you can also play for smaller weeks until your financial situation improves.
