Rules on Wikipedia, both the complex Bao and the simpler Oware and Kalah can be played with the Green Box. There are not enough cubes of one colour, so one player has to use yellow and red, and the other player uses blue and green.
Kalah Setup Edit
The color of the cubes does not matter for Kalah. The setup is made with two rows of 6 neutral tiles. At each end of the rows is one player specific "store" field. For a beginner's game 3 cubes are places on each neutral field. Placing more cubes makes the game more complex.
