About Reversi Online: Quick Duel
Reversi Online: Quick Duel puts you across a midnight-blue board from a live opponent in seconds. Press Quick match and the lobby pairs you with another player; if nobody shows up within twenty seconds, a sharp AI fills the chair so you can start immediately. Colours are assigned at random each game and Black moves first. Trap your rival's discs in straight lines to flip them, fight for the corners that can never be taken back, and avoid the squares next to them that hand corners away. Each move has a turn clock shown around your avatar; if it runs out, a sensible move is played for you, and a dropped connection can rejoin the same seat within a minute. The deep blue felt is framed in dark lacquer with gold lines, and every flip turns over in a quick cascade so you can follow exactly what changed. After the final count you can rematch the same opponent, look for a new one, or send a friendly quick message. Online play requires a free sign-in and wins earn leaderboard points. Before you sign in, practise against the hard AI, which reads several moves ahead and plays the endgame perfectly.
How to play
Press Quick match to find an opponent (sign in first), or play the AI. Tap a glowing dot to place a disc and flip every trapped line. No legal move means you pass. Most discs at the end wins. Resign with the flag; chat with quick phrases.
