Folly

Freya's Folly - an older game (2005) that has always been underrated in my opinion.  

Players send their team of dwarves down the mines to collect jewels - the better ones being deeper, of course - then the collected jewels are made into jewellery for points (or penalties, if not completed).  

It's a race to finish first so there's a continual trade-off between speed and potential score value.
