BLOCKADE VS REVERSI

Blockade (also known as Cul-de-sac) is a strategy board game for two players with the motto "beat the barrier". It's played on a board with an 11x14 grid of spaces, barriers and 2 mobile playing pieces per player. The object of the game is to maneuver ones pieces around barriers and into the opponents starting spaces. The game is long out of production. Blockade was created by Philip Slater in 1975. In United States, it was published by Lakeside under the name Blockade. In France, Germany, Sweden, and United Kingdom the game was published by Lazy Days under the name Cul-de-sac (French, translation dead-end). The rules are simple, but it provides an interesting and deep game. Each player are given 2 pawns, 9 green walls (placed vertically), and 9 blue walls (placed horizontally). Pawns are placed on their starting locations on each of the four corners of the 11×14 board. First players' starting location is at [4,4] and [8,4], and the second players' is at [4,11] and [8,11]. The object of the game is for each player to get both their pawns to the starting locations of their opponent. The first to do so wins. On each turn, a player moves one pawn one or two spaces (horizontally, vertically, or any combination of the two) and places one wall anywhere on the board (useful for blocking off their opponent's move). Walls always cover two squares and must be placed according to their color (vertically or horizontally). Pawns may jump over other pawns that are blocking their path. Once players are out of walls, they keep moving pawns until one wins.

Reversi is a strategy board game for two players, played on an 8×8 uncheckered board. It was invented in 1883. Othello, a variant with a change to the board's initial setup, was patented in 1971. There are sixty-four identical game pieces called disks (often spelled "discs"), which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color. The objective of the game is to have the majority of disks turned to display one's color when the last playable empty square is filled. Goro Hasegawa claims that the origin of Reversi/Othello dates back 5,000 years. However, there is solid evidence that a game similar to Reversi/Othello existed since the 19th century. Each of the disks' two sides corresponds to one player; they are referred to here as light and dark after the sides of Othello pieces, but any counters with distinctive faces are suitable. The game may for example be played with a chessboard and Scrabble pieces, with one player letters and the other backs. The historical version of Reversi starts with an empty board, and the first two moves made by each player are in the four central squares of the board. The players place their disks alternately with their colors facing up and no captures are made. A player may choose to not play both pieces on the same diagonal, different from the standard Othello opening. It is also possible to play variants of Reversi and Othello where the second player's second move may or must flip one of the opposite-colored disks (as variants closest to the normal games). For the specific game of Othello, the game begins with four disks placed in a square in the middle of the grid, two facing white-side-up, two dark-side-up, so that the same-colored disks are on a diagonal. Convention has this such that the dark-side-up disks are to the north-east and south-west (from both players' perspectives), though this is only marginally consequential: where sequential openings' memorization is preferred, such players benefit from this. The dark player moves first.
