The Galton machine (QUINCUNX) is named after Sir Francis Galton, an English mathematician and statistician who developed it in the late 19th century to explain some statistical concepts. Sir Francis Galton was a cousin of Charles Darwin and was greatly influenced by Darwin’s work on evolution and natural selection. QUINCUNX: The word comes from the Latin ‘quinque,’ five. The distribution of the pegs resembles that of the dots on the No. 5 face of a die.

How to play

Pour the balls into the opening at the top. Try to guess how they will be distributed and why. Once all the balls have fallen and are in place, open the base and have the balls collected in the bucket. Repeat the operation. In the version made for DIN and offered here, there is a lever that, when operated in a vertical motion, allows the balls not to block the funnel opening.
