BrainTwister (1989)

BrainTwister A fascinating game of logic and reasoning. Two to four players compete trying to solve sequences of colorful geometric shapes. A sequence-solving game. Players are shown a series of colored geometric shapes and they try to guess the color and shape of the sixth figure of the series. Puzzles range from the very simple to the very difficult. Depending on a die roll, players are shown only the first three, four, or five figures of the series; they then "bet" which figure will turn up sixth (once a player bets on a shape and color, no one else can make the same guess). In some cases, figures are shown one at a time, with players making bets after each unveiling. Challenging, educational, and fun.
