3 variants of the flanking capture game. Standard Othello, Anti-Reversi (fewest discs wins), and the compact 6x6. One plugin parameter inverts the win condition entirely.
Reversi demonstrates the power of parametric rules. Change one value and the entire strategy inverts. The engine handles both without branching.
The classic 8x8 game played in international competition since 1977. Place discs to outflank and flip your opponent's pieces. Most discs wins when no moves remain.

The misere variant. Win condition inverted: fewest discs wins. One parameter change (winBy: "fewest") transforms the entire strategic landscape. Corner control becomes a liability.
