iReversi.com has a free online version of reversi you can play from your web browser. Reversi is the original name for the board game Othello, which is a trademark of the Pressman Toy Corp. In this version you play as the black color against a computer opponent that plays as white. You can place a black chip anywhere on the game board next to a white chip that has a series of white chips in the same row, column, or diagonal, but with a terminating black chip. For detailed instructions visit our Reversi Game Tutorial page.
Have fun :)
