In Cubist, you and your opponents are architects competing to build a grand and inspiring new Modern Art Museum including its interior sculptures or installations. Aptly enough, your building materials are cubes, or more precisely, dice!
SiXeS is about things that are similar and different. Play six rounds, think of six things each round. and try to predict what you will write that will match, or not match, what the other players write, depending on whether you are in a "match" round or a "unique" round.
