Kalahari consists of a triangular wooden board with cups numbered 0-9. Place the ball in cup #0 and flip it to cup #1, then #2, in order. Once you get to 9, you go to 1-0 for ten, 1-1 for eleven 1-2 for twelve and so on. The goal is to see how high of a score you can get without dropping the ball. When the ball is dropped, or land in the wrong cup, you must start over. Once the basic game is mastered, you can change to odd or even numbers only or in descending order.
