This is interesting because the UK lottery made a very similar change, with the same effect - higher odds of winning any prize, lower odds of winning. They also doubled the entry price to £2. They changed the numbers to choose from 1-49 to 1-59, and added a prize for matching any 2 (apparently 1 in 10.3 odds) of a free lucky dip (ie another play). It'd be interesting to know the distribution of people's picks now - I know that my parents use the same numbers they always have, all in the 1-49 range. Obviously lucky dips are more fair, I'm not sure which is more common though.
