Throw Down Seven

From BoardGameGeek:

A polyhedral dice game for one or more players. A "press your luck" game where players start with a standard set of seven polyhedral dice then roll repeatedly, setting one aside after each roll in an attempt to achieve a low score. Dice are eligible to be set aside, or "thrown down", based on rules involving the value rolled and the maximum face value on that die. The game includes a fantasy story that correlates the different dice to different evil creatures such as ogres, trolls and necromancers. Available on Etsy. -description from the publisher
