## Reversi

Reversi is a two-player abstract strategy game played on a grid board with double-sided discs. Players take turns placing discs to flank and flip their opponent's pieces. The player with the most discs when no legal moves remain wins.

Invented by Lewis Waterman and John Mollett in England around 1883. Public domain. World Reversi Championships have been held annually since 1977.
