Othello (1986 video game)

Othello or Othello World for Game Boy, is a video game developed by HAL Laboratory, made for the Nintendo Entertainment System.
Versions of the game were first released on home consoles by Philips Magnavox on the Odyssey 2 as Dynasty in 1978, and later on the Atari 2600 in 1981. Othello is based on the board game Reversi, which was marketed as Othello.

Gameplay

It is played with two-sided chips, also called discs, on a board. The player can choose between black or white chips. Games are either player versus computer or player versus player. The goal is to end the game with as many chips showing your color as possible. To do this, players must sandwich their opponents' chip between a piece of their own color already on the board, and the piece being played. The game has four skill levels when playing the computer, as well as a hidden fifth level if you beat the computer on level four.
There is supposedly a slot machine game that is revealed when pressing Select + A at the main menu screen, but some users have reported that nothing happens after the word "slot" shows up.
