What is avalanche mode in mancala and how does it affect gameplay?

In mancala, avalanche mode occurs when a player's last stone lands in an empty pit on their side of the board. This allows them to capture all the stones in the pit directly across from it, as well as any stones in the pit next to it. Avalanche mode can significantly impact gameplay by giving a player the opportunity to capture multiple stones at once, potentially shifting the balance of the game in their favor.
