  How to Play
This is the original Reversi using the original rules (possibly the only one on the internet!)  Each player has 32 pieces and the first two on each side must be played in the centre squares.  Each piece is blue on one side and yellow on the other.  You are blue and play first by placing a piece on one of the centre squares.  When the centre is full, play on any square on the board where you 'sandwich' at least one yellow piece between the piece you are playing and a blue piece already on the board.  All trapped yellow pieces will be turned over to blue. Play continues in turn.  If a player cannot flip any of the opponents pieces, he must pass and his opponent plays again.  This can happen more than once. When neither player has a legal move (usually when the board is full but not always) the game ends and the winner is the player with the most pieces of his colour showing. The game is set up so you can see your possible positions to go highlighted.
Hint: Go for corners and edges!

History
Reversi, (modified slightly and marketed as 'Othello',a registered trademark of Tsukuda Original) is a classic board game.  It is believed to have been invented by Lewis Waterman around 1870 (John W. Mollett invented a similar 'Game of Annexation' about the same time but with a cross-shaped board) and Walter H. Peel wrote a book, Handbook of Reversi, published by Waterman's firm Jacques and Sons in London in 1888.  Around 1970, Goro Hasegawa, wrote a book called How to win at Othello.  The book is currently out of print, but credible sources indicate the best way to use this book is to give it to your opponents.  He set the four start pieces in the centre before play begins and allowed each player as many pieces as they need.
Computer programs such as Logistello developed by Michael Buro can analyse up to ten moves ahead and are now stronger than human players.
