El Shaddai: Zero Nine Reversi

About the Game

Zero Nine Reversi reimagines the classic board game with a bold twist: every stone has HP.

In standard Reversi, flipping a stone is absolute. In Zero Nine Reversi, flipped stones lose 1 HP. When HP reaches zero, the stone is purified and removed from the board. This single change transforms every match into a battle of attrition where positioning, timing, and resource management matter as much as territory.
