How to play Reversi...
The objective is to have the most pawns at the end of the part.
To each turn, you place a pawn of your color on an empty space. You can place a pawn only at the places where you capture at least one of those of your adversary.
You capture one or more pawns of your adversary if they are between one of your pawns and that which you pose on the plate.
You can capture in the eight directions at the same time - to the top, towards bottom, on the right, on the left, in the four diagonals.
The play is finished when all the boxes are filled - or when none of the two players can pose pawn. If a player cannot place a pawn, but the others can it, it must then jump its turn.
You must play each time you have at least a possibility: you cannot “pass”, perhaps even if you would prefer it…
The number of your pawns to and from, and the full number of the parts which you hold is less important (except worms end) that of their position.
The sites on the edges have more value than the sites inside, quite simply because there is less of possibilities to capture them.
In the same way, the four corners are the most invaluable sites on the plate, because they cannot be captured.
This play was invented in 1883 by English Lewis Waterman, and knew an important popularity in England at the end of the 19th century. This play is mentioned in an article of 1895 of NewYork Times: “Reversi is a little like Go Bang, and is played with 64 parts.
This play is from now on in the public domain (contrary to one of its versions called Othello).
