Kubb, also known as viking chess. I will be honest and had to research it, as I had never heard of it before. I will have to watch some more YouTube videos so I know the rules better. This is a bada** cool gift. My Santa did some sufficient stalking to know that I love all norse. I know this will get lots of use, as it is portable enough to take camping, or tailgating, or throw in the truck to take to our next backyard BBQ. Move over cornholers, I ain't tossing sacks of corn, but femurs and skulls! Hats off to my Santa, he was very creative with this one. I am a very happy camper :) my Santa also kept in touch with me throughout the process, as I like to do that as well + 10 for sure. I know that my campground spot will have lots of looky lookys wanting to try this.
