I worked with a nationwide lottery game in Sweden called Limbo around 2005-2006 that used this concept. I believe the winner each day won around $1000 and had the ability to turn it into $10000 in a weekly final doing the same game in a tv-studio.

The game was completely shut down after people in a small little town won three times in a row and they started to suspect foul play. Turned out to be the local store asking people to join and the store distributed the numbers for the people to make sure they had an even distribution across a huge range.
