I was looking through some websites that I have saved to my favorite and came up this one that explaines how to make your own Mancala game.
I did this when my two older kids were probably 7 and 8. It is a great game and they were occupied with it for hours at a time and actually didn't really get tired of the game like kids usually do. '
The website explaines how to plain the game if you don't already know. Give it a try and let me know how you like it.
