Centerfold Squares
Centerfold Squares, retitled Centrefold Squares in Europe, is an erotic puzzle game originally developed and self-published by Artworx and released in 1988 for the Amiga, Atari ST and DOS. The game is a variation of Reversi where rectangular sections of an image of a nude model are revealed as the player earns points. "Centrefold Squares" was published by CDS Software in Europe, and published by Proein S.A under the original American title in Spain. Gameplay. "Centerfold Squares" is a variation of reversi referred to as 'Double-Up' that is played on a ten by ten grid; four  counters of two opposing colors are placed in the center in a two by two alternating pattern. The game is played against an AI of varying difficulty, and each player takes turns placing counters on the board next to an existing counter, and if a player surrounds an opposing counter with two counters of their own color, that counter then becomes their color. "Centerfold Squares" has special squares in the grid, which activate different effects when a counter is placed on them: red squares subtract points, green squares give extra points, and yellow squares allow the player to take another  turn. There is also a '???' button which takes up a player's turn in exchange for a random effect, such as large point changes or instant wins or losses. Points are earned through the player changing opposing counters to their color, and earning a set number of points (determined at the beginning of the round) will win the game. The points are then used to remove one of the black tiles covering a digitized image of a nude model - each tile has a set number of points required to remove it. If the AI wins, an already revealed tile is  covered up. "Centerfold Squares" has twelve female model photos in the base game. An expansion disk with eleven additional model photos was released. Each photo is marked with the difficulty of the AI, and the difficulty is tied to the unlockable photo as opposed to being selected by the player. The available difficulty levels are Below Average, Average, and Above Average. Ports. Sound effects as well as a save feature are limited to the MS-DOS version. It supports CGA, EGA, and Tandy Graphics Adapter modes. The Amiga version may be launched from the workbench. The Atari ST supports the  use of a second disk drive to run both game disks at once.
