Mad Cave Bird games, LLC, is a maker of fine quality wood board games for the entire family! Founded in 2006 our small family company makes games that are not only fun but are educational and challenging too. ColorKu was our first game and is great! We now make expansion puzzle packs for ColorKu and will be introducing a brand new game, Tic-Tac-Ku this year. It too is a high quality wood board game with wood marbles and presents a whole new twist to take the old tic-tac-toe game to a new level of fun skill and strategy!
