@Kimilsung it's a free daily lottery website. You are presented with a map of your local area and you have to select a number of little patches from the map each day to build up your overall patch. Each little patch is an entry into the daily lottery, I believe, so the more patches you have, the better chances of you winning. There is a map showing the daily winner and you need to check this each day to see if you have won. It isn't a huge amount of money but it's a bit of fun and there's a cookie story snippet to read each day that get you bonus patches.
If you feel like signing up, I'd be really appreciative if you used my referral link. I get extra patches and you'd get £5 personal bonus (which you get when you win the daily patch).
