A Victorian strategy classic
What is Reversi?
Reversi emerged in England during the 1880s. Its enduring idea is remarkably compact: trap a line of opposing pieces between two of your own, then flip the captured line to your color.
The rules are easy to learn, but corners, mobility, and timing create deep strategy. Nadda preserves the standard 8×8 board and adapts it for instant local or online play.

Quick guide
How to Play
Place and surround
Place a piece so one or more continuous opponent pieces are trapped between the new piece and another piece of your color.
Flip in eight directions
Every legal move flips at least one opposing piece. A single move can capture horizontally, vertically, and diagonally.
Protect the corners
Corner pieces cannot be surrounded. Use the edges carefully and avoid giving your opponent an easy corner.
Control the final board
If a player has no legal move, their turn is skipped. The player with more pieces when no moves remain wins.
