Al-Khwarizmi

Al-Khwarizmi is a number based memory game for two players only that also has some resemblance to Ralph Baer's classic game SImon. The goal of the game is to push on the number keys as the computer selects them (There are only nine). The computer keeps adding numbers until you get one wrong, and then it goes to the second player. The player with the highest score at the end is the winner.

This game was developed by Robert Young and Paul Copeland and published in 1983 by Penguin Books as a type-in listing in their book "The Penguin Book of Commodore 64 Games"
