Here's information that Gators passed on to me about when the top prizes were claimed on $20 Lucky For Life. The FL Lottery currently advertises two $200k/yr for life prizes remaining, and 4 $50k/yr for life prizes. The game appeared to be 78% sold through in August. I'm not sure how much has changed since then, I'd imagine at least a few percentage more sales. If you're curious, email the FL Lottery asking for an up to date instant liability report.

The big gap between prizes 2 and 3 on the $50k/YR for life makes me suspicious about one prize being lost, or unclaimed. As far as specific ranges to target, I'm not sure. I've seen the book go up to the 535k range. The 520k-530k range seems to be about around where I'd expect the next $50k/YR prize to pop up. Then again, with this game being 50 tickets/book, hard as hell to scratch, no bar code, it is one of the least popular tickets. I've talked to a retailer who told me he had an active book of this game up for 7 months before selling off the book, and refused to ever order it again because of that lol.
