BLOX-O GAME By Lubbers & Bell Mfg. Co. - 1923 MADE IN THE USA in IOWA! Game Description: This variant of adds "blocking" positions to the standard board. Each time a player gets three-in-a-row, he removes a piece of his opponent, but also adds a blocking pin to the line with his three-in-a-row. This block then prevents said player from making another three-in-a-row along the same line. This additional element removes some of the simplest winning patterns from the standard game. The gameboard (from 1923) includes extra spaces for the blocking pins. This is a real gem, and for being 100 years old is in really nice condition.
