Gem Getter Pro

From BoardGameGeek:

In Gem Getter Pro, you and your friends compete to dig the most efficient mine and become the gettingest 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! Oil keeps the digging machines running longer with bonus digs, while natural gas offers flexibility when choosing a future dig pattern. 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! -description from the designer
