What is Reversi (Othello)?
Reversi is a game where players take turns placing stones on the board, flipping their opponent's stones to their own color by surrounding them. It is also known as Othello.
Three Basic Rules
- Each player aims to have the most stones of their color on the board at the end of the game.
- By surrounding your opponent's stones vertically, horizontally, or diagonally, you can flip them to your own color.
- You can only place your stones in positions where you can surround your opponent's stones ( valid moves ).
- You will win if you have more stones than the opponent has when no more moves are possible, or the opponent runs out of time or resigns.

Features of Reversi Web
A free Reversi (Othello) game that you can play instantly on the web. It features AI matches, online matches, and a Reversi board mode that simply displays the digital board.
Reversi Board Mode
This mode is perfect for playing face-to-face. Ongoing matches and settings are automatically saved, so you can continue playing even if you reload the page. This is the first mode that was made on this site.
Below the board, you can see the current stone counts and (if enabled in Settings) the game evaluation are displayed. The evaluation value reflects how a powerful Reversi AI perceives the board. You can choose to display it when studying moves alone, or hide it when playing with family or friends.
Play in App Mode
You can add it to your smartphone, iPad, or PC home screen and use it like an app. Since it's a web app, it takes up almost no storage and only takes a few seconds to set up. The fast startup and offline functionality are nice bonuses.
Development Process of Reversi Web
The reason I started creating this site was that I once had trouble finding a site where my family could play Reversi together.
During the development process, I made it a point to interview actual users and improve the site based on their feedback. Since then, I have continued to make daily improvements, such as adding a unique online match mode and a powerful AI. I will never forget the warm responses I received from both inside and outside the university.
I will continue to strive to provide a better web service, and I hope you will continue to enjoy playing it for a long time to come.
