Looking for a game that’s "a minute to learn, a lifetime to master"? Othello Online (also known as Reversi) on SliceGames is the perfect arena for tactical minds. Whether you want to challenge our smart AI bot or battle a friend in local multiplayer, our sleek, web-based board ensures a smooth experience without any annoying app downloads.
Othello is all about territory. The game starts with four discs in the center. Your goal is to "sandwich" your opponent's discs between two of your own color. Once trapped, those discs flip and become yours! The player with the most discs on the 8x8 grid at the end wins the match.
Step 1: Place your disc so it traps one or more of your opponent's pieces in a straight line (horizontal, vertical, or diagonal)
Step 2: All trapped pieces are immediately flipped to your color.
Step 3: Plan your moves to gain control of the edges, which are much harder for your opponent to reclaim.
Every move you make must result in at least one of your opponent's discs being flipped. If you don't have a move that can capture a piece, you must pass your turn. The game concludes when the entire board is filled or when neither player can make a legal move.
Beginners often try to capture as many discs as possible early on—don't fall into this trap! Othello is famous for massive late-game reversals. The key is positional play. Owning the right squares is much more important than having the most discs in the first few rounds.
Claim the Corners: The four corner squares are the most powerful spots on the board. Once you take a corner, it can never be flipped back.
Limit Their Options: Try to keep your pieces in the center during the early game. This forces your opponent to move toward the edges, giving you the chance to strike.
Think Two Steps Ahead: Anticipate where your opponent will move after you flip a row. Don't give them an easy path to a corner.
