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.

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.
