Kalaha is one of the oldest known games of the world to still be widely played today.
A move is made by taking all stones from a pit on your own side and sowing them one-by-one in counterclockwise direction. Your own kalaha (big pit; Player 1 top » big pot to the left and Player 2 bottom » big pot to the right) is included in the sowing, but the opponent's kalaha is skipped.
There are three possible outcomes of a turn:
1.) Your turn ends in your own kalaha (big pot): It is your turn to move again.
2.) The sowing ends in an empty pit on your own side: All stones in the opposite pit (on the opponent's side) along with the last stone of the sowing are placed into your kalaha and your turn is over.
3.)
Otherwise (the sowing ends on the opponent's side or in a nonempty pit on your own side): Your turn is over.
If all pits on your side become empty, the opponent captures all of the remaining stones in his pits. These are placed in the opponent's kalaha and the game is over.
You win the game when you have more stones than your opponent. If both players end up with the same amount of stones, the game is tied.
