The word mancala means to transfer in Arabic. This game, which by some estimates is 7,000 years old, challenges players to move pieces from bin to bin in its special board. Many rule variations exist, and mancala is played in some form in almost every African country.

Used a hot iron to remove then old leds and replaced SMD 0603 Red Leds, below shows one segment replaced and lit up.
