El Shaddai: Zero Nine Reversi

Zero Nine Reversi is a board game that puts a bold twist on classic Reversi. Every stone has HP.

The game includes two ways to play: "Classic," a deep single-player challenge, and "Online," where you pick a character and battle other players.

Classic

In normal Reversi, flipping a stone is the end of the story. In Zero Nine Reversi, a flipped stone loses 1 HP. When its HP reaches zero, the stone is purified and vanishes from the board. This simple change turns every match into a battle of attrition, where positioning, timing, and resource management matter as much as territory.



Features

A versus mode where you choose a character and fight. On top of stone HP, it adds the "BUMP & BURST" rules and a unique ability for each character.



Features

• 40+ Characters — Each has their own HP, attack power, and unique ability. Charged, automatic, conditional and more — each ability type changes how you fight.
• Online Battles — Take on players around the world in Random Match, or invite friends with a room code. Your record and ranking are saved.
• Team Battle — A 2-vs-2, four-player mode. Work with your ally to take control of the board.
• Play Offline Too — Battle the CPU, play 2-player on the same screen, or play Team Battle. Choose an 8×8, 10×10, or 12×12 board.
• Archive — Spend the Gold you earn in battle to unlock characters, titles, effects, and backgrounds.
• Daily Challenge — Complete daily tasks to earn points and claim rewards.
