Computer Challenge © 1977 Radofin Electronics.
A computer version of Connect Four. Two players can play against each other or one player can play against the computer with three skill levels and two board sizes (7x6, 8x6). Just as in the popular board game players insert tokens and try to match up four in a row. Unlike tic-tac-toe a token cannot be placed anywhere, but only in the bottom-most available row in a column.
Alternate titles for other AVPS systems: Challenge!, Four-in-a-Row, Four in a Row.
Released by Interton as "Intelligenz II [Cassette No. 15]" for the VC 4000.
