Mancala, also known as Kalah, is a free iPhone game developed by Sergey Skosyrev. The game is based on an ancient board game, where players pick up marbles from any of the bottom holes and move them counter-clockwise. If your move ends at your home hole (right one), you can move again. The game ends when all six holes on either side are empty, and the winner is the player with the most marbles in their home hole.

Mancala offers a simple and intuitive interface, making it easy to play for both beginners and experienced players. The game also features a single-player mode against the computer, as well as a multiplayer mode for two players. The graphics are well-designed and visually appealing, and the game runs smoothly without any glitches or lag. Overall, Mancala is a fun and challenging game that is perfect for passing the time and improving your strategic thinking skills.
