## What is Reversi Trio?

Reversi Trio is a fresh take on Reversi with 3-player battles, Spectator Mode, and Mirror — the AI that learns your style.

■ A Fresh 3-Player Twist on Reversi
Three players compete for the board using blue, white, and red pieces. Perfect for friends and family gathered around a single iPhone or iPad.

■ Spectator Mode
Sit back and enjoy AI-vs-AI matches. Watch how different AIs think in both 2-player and 3-player battles.

■ Mirror — An AI That Learns From You
Unlock by beating Crank (Hard) 3 times. Mirror studies your game history using on-device machine learning and mimics your play style. Can you beat yourself?

■ AI Characters to Challenge
Distinct AI opponents await, each unlocked by defeating the previous:
• Pip (Easy)    — Great for beginners
• Bolt (Normal) — Unlocked after 3 wins vs Easy
• Crank (Hard)  — Requires real strategy
• Titan (Expert)— Uses iterative deepening search
• Draco (Master)— The ultimate challenge

■ Multiple Game Modes
• 1 Player vs AI (choose black or white)
• 2-Player local match
• 3-Player battle (mix of humans and AIs)
• Spectator mode — watch AIs battle each other (unlock after 3 Expert wins)

■ 4 Beautiful Themes
Choose from France, Italy, and Germany tricolor themes, plus the soft Sakura theme (additional in-app purchase). New themes unlock as you rack up wins.

■ Stats & Achievements
Track wins, streaks, and best streaks per AI difficulty. Defeat stronger opponents to unlock new challengers.

■ Free to Play
Completely free to download and play. An optional one-time purchase removes all ads permanently.

Perfect for: Reversi fans, board game lovers, anyone looking for a fun multiplayer game to enjoy with friends and family.
