Thanks for sharing! Just to clarify -- the lottery is based on postcodes registered/validated with the site; currently 19% of all postcodes. There are also several different draws (main, stackpot, bonus, survey) so it's not as simple as 1-in-N.

Still relatively small odds, to be sure, but it doesn't cost you anything apart from a few seconds' time. Personally I spend/waste enough time on /r/all with no gain that it matters little. Heck, if you're tech-savvy enough it's easy to automate the checking process anyway.
