Short description
A unique Reversi game set in the world of El Shaddai. Stones have HP that decreases when flipped, adding deep strategy to the classic board game. Unlock 40+ stories, characters, and special rules as you climb the ranks.
About this 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. FEATURES HP-Based Reversi — Stones start with HP 0–9. Flipped stones weaken and eventually vanish. Every move has consequences that ripple across the board. 40+ Unlockable Stories — Discover the tales of angels, fallen ones, and the world of El Shaddai as you earn ranking points. Each story features original character art and cinematics. Multiple Board Sizes — From the compact 6×6 Mini to the classic 8×8 Reversi and the cross-shaped 12×12 Annexation board. Special Rules — Unlock unique modifiers like Bocchi Enoch, Metatron's Wave, Gariel's Light, and more. Each rule changes the game in surprising ways. 5 AI Difficulty Levels — From Easy to Death. The hardest AI will punish every mistake. Daily Challenge — A new puzzle every 12 hours with fixed board, HP, and rules. Online Ranking — Compete globally with a rating system that rewards skillful play. Rich Lore — Set in the universe of El Shaddai: Ascension of the Metatron, featuring beloved characters like Enoch, Lucifel, and Michael. Keyboard & Mouse Support — Full desktop controls with keyboard navigation and mouse hover preview.
