Othello, also known as Reversi, is played by trapping opposing discs between your own and flipping them to your color. Play Othello (Reversi) free in your browser against adjustable AI. No download or account.
Four AI levels that play for mobility, corners and endgame parity. Master Hint marks the move and counts exactly how many discs it flips, so you can see the swing before you commit.
How You WinHave more disks of your color on the board than your opponent when the game ends. Only that final count matters — a middlegame lead means nothing, since the last few moves often flip entire regions.
