Mancala
Mancala is one of the oldest known games to still be widely played today. "Mancala" is a generic name for a family of two-player turn-based strategy board games played with small stones, beans, or seeds and rows of holes or pits in the earth, a board or other playing surface. The objective is usually to capture all or some set of the opponent's pieces. Versions of the game date back to the 7th century, and evidence suggests the game existed in ancient Egypt.
Tai shogi
Tai shogi (泰将棋 "tai shōgi" or 無上泰将棋 "mujō tai shōgi" "grand chess", renamed from 無上大将棋 "mujō dai shōgi" "supreme chess" to avoid confusion with 大将棋 "dai shōgi") is a large-board variant of shogi (Japanese chess). The game dates to the 15th century and is based on earlier large-board shogi games. Before the discovery of taikyoku shogi in 1997, tai shogi was believed to be the largest playable chess variant, if not board game, ever. One game may be played over several long sessions and require each player to make over a thousand moves. It was never a popular game; indeed, a single production of six game sets in the early 17th century was a notable event.
