Today's die is a wooden six-sider that I picked up while cleaning up at my in-laws. It measures 15mm. One side has a purple dot, one side has a black dot. two sides have a green dot, and two sides are blank. It is well used. I have no idea where it came from. My guess is that it is from a European family game made in the 1980s. If you know what this die was originally used for, please comment.
