Mancala is a type of game where two players take turns using small stones, beans, or seeds placed in holes or pits on a board. The goal is usually to capture all or some of the other player's pieces.
People have been playing versions of this game for a really long time, even going back to ancient times like Ancient Egypt, over 2000 years ago. It's one of the oldest games that people still play today.
You can play it with dried baens, pebbles or whatever you like or you can print the added gems, pebbles, hearts or beans (at least 48 in total).
Here is a great tutorial I found on YouTube:
