Othello Game
This page is a browser-based Othello and Reversi game with a teletext-style board.
It is for players searching for Othello online, Reversi against CPU, flip-disc games, or simple strategy board games.
The working game remains on Page 1 so the board, controls, output and pager stay clear and readable.
Corners: take them whenever possible.
Avoid X-squares: diagonals beside empty corners are risky.
Mobility: limit the CPU’s legal moves.
Edges: secure edges after corner control.
Late game: parity and move order matter.
