Kubb (also spelled "koob") - sometimes known as Viking Chess - is a Scandinavian lawn bowling game that, like its brethern bocce, horseshoes, cornhole, and the like - involves two teams standing on opposite sides of a field throwing things at other things. And those things they throw - the game pieces - are some basic wooden shapes...meaning, it's a super easy DIY project you can make at home.
This game set by Matt Pierce was crafted from a single 4x4" post and some birch dowel rods, both of which are easily found at your local home improvement center. Make some cuts and sand, gather with some friends, and head outside.
The rules are simple. Here's a quick video that explains how it works:
