There are some exceptions to the basic rules which can change how the game is played. When you are dropping stones, if you drop a stone into your own mancala and it happens to be the last stone in your hand, then you get to go again and pick more stones from another hole.
If you drop a stone in one of your own empty holes and it happens to be the last stone in your hand, then you get to take every stone in the hole directly facing that stone and place them in your mancala.
