unlocking extra levels

[stig]

Just spent the weekend enjoying the best ?10 ever spent ,

Have finished the 50 levels and have extra levels 1-7
to unlock the other levels I guess i need to get higher scores on
some levels, but what levels and what scores do i need , anyone know ?

From what I remember you get a new extra level for every $1000 of your total score. So it doesn't really matter in which level you get a higher score, but those where you can save $1000 are obviously more lucrative than those where you have to try hard to save $10
