Masterwits

Masterwits is a version of Mastermind for the VIC-20 home computer. The object is to guess a random combination of four colors determined by the computer out of six, and the player must use the keys 1 through 6 corresponding to each color listed at the bottom of the keys. Once the player makes their selection, one of two arrows will appear. A black up arrow indicates the correct color in the correct position, while a white up arrow indicates the correct color, but in the wrong position. When the player has four black arrows, they will win the game.
