Rules: At the beginning of a player's turn, they select a hole with seeds that will be sown around the board. This selection is often limited to holes on the current player's side of the board, as well as holes with a certain minimum number of seeds. In a process known as sowing, all the seeds from a hole are dropped one-by-one into subsequent holes in a motion wrapping around the board. Sowing is an apt name for this activity, since not only are many games traditionally played with seeds, but placing seeds one at a time in different holes reflects the physical act of sowing. If the sowing action stops after dropping the last seed, the game is considered a single lap game. Multiple laps or relay sowing is a frequent feature of mancala games, although not universal. When relay sowing, if the last seed during sowing lands in an occupied hole, all the contents of that hole, including the last sown seed, are immediately resown from the hole. The process usually will continue until sowing ends in an empty hole. Another common way to receive "multiple laps" is when the final seed sown lands in your designated hole.
