Sid Sackson (1920-2002) is considered by many one of the greatest game designers of all time. A civil engineer by training, he devoted his time, later in life, to playing, collecting, and designing games of all kinds. His financial game Acquire was among the first published in the famous 3M bookshelf game series, and it is still in publication. Sackson created another winner in 1980, when Parker Brothers published his dice game "Can't Stop." A favorite of serious gamers, Can't Stop is a dice game in which players score points on a board using different combinations of the roll of four dice. Risk of losing space on the board increases as players continue to roll. They may stop any time, but sometimes, to take a chance, they just can't. Parker Brothers only published the game for a short time but in later years, other makers brought out new editions. Can't Stop can also be played with dice and a pencil and pad. Some European versions employ that mechanic.
