Play Reversi online for free, the strategy game where one move can flip the whole board. Place a disc so that it traps your opponent’s discs in a straight line and they all turn to your color. You play black and move first on an 8×8 board, against the computer or a friend. Valid moves are marked with dots and a counter shows how many discs each side has, so beginners can jump straight in.
How to play
- Black moves first. Place a disc so that it traps one or more opponent discs in a straight line between your new disc and another of yours.
- All trapped discs are flipped to your color.
- If you have no valid move, you must pass.
- When neither player can move, the player with the most discs wins.
Controls
- Click or tap a square marked with a dot to place your disc there. Dots show every valid move.
- If you have no valid move, your turn passes automatically.
- Use Undo to take back a move, or New game to start again.
Tips and strategy
- Take the corners whenever you can. A disc in a corner can never be flipped.
- Avoid the squares right next to an empty corner. They often hand the corner to your opponent.
- Having more discs early on is not always good. Fewer discs can mean more choices later.
- Try to limit your opponent’s moves. A player with no good options is forced into bad ones.
- Edges are strong but not always safe. Check whether your opponent can flip the line.
Game modes and difficulty
Play against the computer on Easy, Medium or Hard. Easy plays loosely and lets you learn the flipping rules, Medium looks for good captures, and Hard values corners and edges and plans ahead. Choose 2 Players to play with a friend on the same device. A disc counter always shows the current score.
History and background
Reversi was invented in England in the late 19th century and quickly became a popular parlor game. The rules are simple: trap your opponent’s discs between two of yours and flip them over.
In the 20th century a version with a fixed starting position of four discs in the center became the standard for competitive play, and international tournaments are still held today. The game is often described as taking a minute to learn and a lifetime to master, because the board can change completely in the last few moves.
