CHECKERS VS SECTOR 41

Draughts (/drɑːfts, dræfts/; British English) or checkers (American English) is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Draughts developed from alquerque. The name 'draughts' derives from the verb to draw or to move, wheras 'checkers' derives from the checkered board which the game is played on. The most popular forms are English draughts, also called American checkers, played on an 8×8 checkerboard; Russian draughts, also played on an 8×8, and international draughts, played on a 10×10 board. There are many other variants played on 8×8 boards. Canadian checkers and Singaporean/Malaysian checkers (also locally known as dum) are played on a 12×12 board. English draughts was weakly solved in 2007 by a team of Canadian computer scientists led by Jonathan Schaeffer. From the standard starting position, both players can guarantee a draw with perfect play. Draughts is played by two opponents, on opposite sides of the gameboard. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent's piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it. Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. When presented, capturing is mandatory in most official rules, although some rule variations make capturing optional. In almost all variants, the player without pieces remaining, or who cannot move due to being blocked, loses the game.

Sector 41 is a board game published by David Long and Michael Lachtanski of Scimitar Games. The game became available for pre-order in February 2009 and was officially released in April 2009. Sector 41 is a turn-based strategy game for two to four players. Game play takes place on a 9×9 grid of face-down tiles, randomly shuffled at the beginning of each game. Players control one mother ship which moves along the edge of the game board. Mother ships can deploy up to three explorer ships onto the face-down grid. Explorer ships are used to discover, mine, and tow deposits of Glynium to their mother ship. According to the game background, Glynium is an unstable power source only found in this sector. Victory is achieved when one player has mined more Glynium than any other player could match. In the case of a tie, the first person to reach that score is declared the victor. Sector 41 was developed from a compilation of game concepts developed by David Long and Michael Lachtanski, the earliest of which go back to the mid-1990s. The name itself is an homage to the popular Area 51 science fiction theme. Play testing began in late 2007 and lasted until production began in late fall of 2008. The face-down tile set up was conceived of to emulate the fog of war mechanism, popular in many computer games. The developers also encourage players to strategically manipulate the board layout for offensive and defensive purposes through the process of "folding space". This game mechanism was inspired by the Dune novels. The lengthy play time in the initial play testing lead developers to create the Guardian figure. The Guardian, described below, acts as a mechanism for rewarding exploration, expansion, and reduced play time dramatically. Additional rules for modifying the Guardian's role in gameplay are available on the Scimitar Games website. Michael Lachtanski designed the game's graphics. Many of the space graphics are based on images from NASA.
