This is for a single drawing only, and scratchers don't count. All varieties of normal lotto games count. Only the money out of your pocket counts. If you use a pool for an example, you can only count your contribution to a pool.
Personally I've only throw about 30 bucks at one, but that was just because it was my birthday. I've only played for a few months though, so I'm sure it will change.
Please don't get into an argument about whether this actually increases your chances of winning.
Just want to hear about what some of you are willing to spend for a more than average attempt, perhaps for a larger jackpot
