Twelve Days is a Christmas themed puzzle game where you must use the hints provided to label all the stockings that have coal. You were promoted to work directly for the head elf after the prior crew messed up and left coal in stockings of children on the nice list. It is twelve days until Christmas and Santa needs this done as quickly as possible. Be warned, the head elf has very little tolerance for mistakes. So make sure to use the X-Ray glasses when there is doubt.
