Play with the ' Reversi ' opening, wherein disks of one color line up parallel to those of the other in the center 4 squares, may still be found among enthusiasts in some places.

It also included the MS-DOS Executive and a game called Reversi.

Reversi ( marketed by Pressman under the trade name Othello ) is a strategy board game for two players, played on an 8x8 uncheckered board.

True Reversi ( that according to the game's original rules ) starts with the board empty and the first 2 moves by each player are played into the middle 4 squares with no disk flips.

Thus Reversi can start with either a parallel or diagonal layout of the first 4 pieces.

Typically computer versions start as per Othello, but the name Othello ( along with certain meaningless features of board design ) is trademarked so that use of the name Reversi is necessary to avoid legal problems.

When the game is played according to the original rules, either player may force play into this Reversi opening.

Though the original rules of Reversi were such that each player was limited to using no more than half of the disks ( those in possession at the start ), this rule has long been out of common practice ; and, if using a physical board and pieces, the player whose turn it is simply retrieves a disk that is in possession of the opponent as needed.

In most cases a game of Reversi reaches an end in which all 64 squares are filled, but positions in which the board is not full and neither player may make a legal move also occur with some frequency.

Later mention includes an 1895 article in the New York Times: " Reversi is something like Go Bang, and is played with 64 pieces.

True Reversi starts with an empty board, and the first two moves by each player are in the 4 central squares of the board.

For the specific game of Othello ( as technically differing from Reversi ), the rules state that the game begins with four disks placed in a square in the middle of the grid, two facing light-up, two pieces with the dark side up, with same-colored disks on a diagonal with each other.

Strategic concepts in Reversi include openings ( and home preparation ), corners, mobility, edge play, parity, endgame play and looking ahead.

It is generally the case that for relatively inexperienced players the opening ( early ) part of a game of Reversi is not something that is very easy to make sense of.

Because of difficulties in human lookahead — peculiar to Reversi because of the apparent strategic meaninglessness of internal disks ( making blindfold games — if not virtually impossible without enormous dedication — more difficult than is the case in, say, chess ) and the attractiveness of the game to programmers — the best Othello computer programs have easily defeated the best humans since 1980, when the program The Moor beat the reigning world champion.
