How to Play
Reversi meets tic-tac-toe.
- Two players: goes first, then , played on a 4x4 grid.
- On each turn, a player takes two actions, in either order:
- Place their symbol on an empty square.
- Invert an opponent's symbol into your own.
- Get 4 in a row — horizontal, vertical, or diagonal — to win. You can win mid-turn after just placing or inverting.
- The 1st move is a half-move: only place (no opponent symbol exists yet).
- The last move once the board is full is also a half-move: only invert.
- If no one wins after the last move, the game is a draw.
