El Shaddai: Zero Nine Reversi first launched for iOS and Android on April 27. The mobile versions were updated alongside the PC release today with online multiplayer support and an archive.
Here is an overview of the game, via its Steam page:
About
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.
Classic features include:
- HP-Based Reversi – Stones have 0 to 9 HP. Flipped stones grow weaker and eventually vanish. Every move ripples across the board.
- More Than 40 Stories – Earn Rank Points to unlock the stories of angels and fallen angels, complete with original character art and movies.
- Multiple Board Sizes – From the compact 6×6 Mini to classic 8×8 Reversi and the cross-shaped 12×12 Annexation.
- Special Rules – Game-changing rules such as Solo Enoch, Metatron’s Wave, and Gariel’s Light.
- Five AI Difficulty Levels – From EASY to DEATH. The top-level AI punishes every mistake.
- Daily Challenge – A new challenge every 12 hours, with a fixed board, HP, and rules.
- Online Rankings – Compete with players worldwide on a rating system shared across all platforms.
- A Rich Story World – Set in the world of El Shaddai, featuring beloved characters such as Enoch, Lucifel, and Michael.
- Keyboard and Mouse Support – Full support for arrow-key board navigation and stone previews on mouse hover.
Online
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.
Online features include:
- BUMP & BURST – When you flip a stone, its HP drops by your character’s attack power (ATK). A stone whose HP hits 0 bursts and frees up its square. A single move can turn the tables.
- Over 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 two-versus-two, four-player mode. Work with your ally to take control of the board.
- Play Offline Too – Battle the CPU, play two-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.
