Othello Reversi

Reversi is an old strategy board game invented in 1883. The game became popular again in the 1970’s as the Othello Game. In this online version you can play against the computer or versus a friend.

 

What is Reversi and Othello?

Reversi and Othello are tabletop board games for two players. The aim of the game is to take over as many as possible of your opponent's disc-shaped game pieces by trapping them between your own.

It’s very easy to learn how to play, but the endless possibilities in tactics and problem solving will keep you playing for years. “A minute to learn – a lifetime to master!”.

 

To start a game:

Press the play icon on the startup screen.

Select game mode: Play against a friend (2 player game) or play against the computer. Before selecting computer, you can alternatively set the difficulty level: 1 star = easy, 3 stars = hard.

When playing against the computer, you will use the black discs (game pieces) and make the first move by placing a black disc on the board. The computer will have the white discs.

 

 

The players take turns in placing one disc (game piece) on the board, with their designated color facing up.

The aim of each move in Reversi and Othello is to trap one or more of your opponent’s discs between two of your own. When you trap discs, you can flip them over and thereby reverse their color to make them yours.

The game is over when both players have placed all their disks on the board, or when there are no more legal moves possible for either player. The player with the most discs on the board is the winner.

 

Example 1 – Black player traps white player’s disc and flips it over:

 

Example 2 – Discs can also be trapped in several directions in one single move, and both in straight and diagonal lines.

 

Rules

In the modern game versions you are only allowed to make a move if you are able to trap one or more of your opponent’s discs.

If there’s no move you can make to trap discs, the move passes back to the other player.

If neither player can make a move to trap the opponent’s discs, the game is over (Stall).

You can only trap discs in straight or diagonal lines.

 

Reversi and Othello game strategy

After playing a few rounds, you will discover basic tactics that can give you an edge. For instance, discs placed in the corners of the board are immune to be flipped for the rest of the game. And discs placed along the edge can only be attacked from the sides. Consequently, it would be a helpful tactic to secure positions like that.

Likewise, it can be a good tactic to avoid giving your opponent the opportunity to occupy those places. For example, try not to be the first one to place a disc on a position next to a corner or the edge, because that will give your opponent a chance to secure that corner or that edge position in a later move.

 

Example 3 – Suggested beginner tactic: Take any opportunity to claim the blue positions. Avoid the red positions in the early stages of the game.

 

Reversi is an abstract strategy board game for two players invented in 1883 in England. The German games publisher Ravensburger put the board game into production. It consisted of a board with a grid divided into 8 columns and 8 rows. Sixty-four disc-shaped checkers served as pieces, colored black on one side and white on the other. Each of the disks’ two sides corresponded to one player. Each player placed their disks on the grid alternately with their color facing up. When one or more of a player’s disk was trapped between two of the opponent’s opposite colored disks in a straight or diagonal line, they would be turned over and thereby change color. The player that had the most disks at the end of the game was declared winner.

 

Various rules were added to the gameplay later to refine the game, and it achieved extreme popularity in the 1970’s, when marketed as Othello the game. The name Othello is a reference to the Shakespearean play, referring to the unfolding drama between Othello, who is black, and Desdemona, who is white. The green board is inspired by Othello valiantly leading his battle in a green field.
