About Gem Getter, from BoardGameGeek:

In Gem Getter, you and your friends will compete to dig the most efficient mine and become the greatest getter of gems. A game is played in 9 rounds. Each round you will... ROLL to determine which polyomino dig patterns are available, DIG your chosen pattern into the mine, and COLLECT heaps of gems with unique scoring conditions. Efficient digging of rows/columns and around boulders will reward you with bonus gems! Find oil to keep the digging machines running a little longer with small bonus dig patterns. There are 8 unique mines to dig in, and 2 roll sheets to choose from for plenty of variety. A game of Gem Getter plays in around 15-30 minutes, and any number of players can join you as long as you have enough sheets!
