A game first, a useful notebook alongside.
Othello Play brings a browser board and a small set of practical guides together. You can play against a computer or share a screen with another person, then follow a rule explanation or strategy idea without installing an app.

What this version includes.
The game is an original implementation of the standard disc-flipping rules. It includes an 8 × 8 board, a fixed four-disc opening, automatic captures and passes, three computer levels, same-device two-player mode, move hints, undo and local browser saves.
The computer uses a limited search algorithm with an evaluation of the board. It is not described as unbeatable or expert strength. Local two-player mode does not include online matchmaking, synchronized rooms or friend links. There are no accounts, player ratings or paid upgrades in this release.

Clear explanations, with clear limits.
Strategy notes are editorial advice. A corner, mobility count or positional heuristic is a useful idea to investigate, not a guarantee that a move wins. We avoid invented player reviews, ratings, awards, traffic claims and claims of official status.
The direct answers, page headings, references and structured data describe the same content visible to visitors. A machine-readable site summary is available for systems that choose to use it. It supplements the guides rather than replacing them.
