This is a traditional Mongolian shepherd's game. All that is required are a set of sheep ankle bones and a grassy field, though it can also be played inside as well. It supposedly pre-dates Chingis Khan. Players take turns flicking their bones that are matching "sides" and collecting the pieces that fall together. Depending upon what part of Mongolia you are from, there might be slight variations on gameplay, but the core system is the same.
