Never enjoyed the market dominance of Connect Four.

This print ad for a Mattel game called Stop Dot comes from the October 30, 1970 issue of Life magazine. The issue cost 50 cents and had a cover story about Dick Cavett, who was then turning out for ABC what still is the best talk show ever produced on U.S. television. Most of the Cavett article focuses on how nervous he was about performing on TV. There is a gallery of work by Austrian photographer Hans-Peter Klemenz. an advertisement for the unfortunately titled AYDS Diet Plan, an article about Ronald Reagan’s presidential aspirations, a piece about separatist violence in Quebec, a story about an Australian Outback tough guy Larry Dulhunty and a long piece about Double Helix scientist James Watson and his search for a cure for cancer.

The advertisement for Stop Dot game refers to the 3-D toy as “that op-art looking thing.” The instructions are as follows: “To win, you have to make a straight row of five dots in five different colors, without putting any dot next to a dot of the same color.”

The product apparently never caught on. According to Boardgamegeek.com, the game was manufactured by Mattel only in 1969. There are two for sale currently on eBay, one for $7.99 and one for $69.95. This particular issue of Life magazine currently sells on eBay for anywhere from $1.99 and $24.99.
