Number Pool

Number Pool is a 1956 design from D. Gottlieb & Company (model 121), credited to designer Wayne Neyens. It was built as an electro-mechanical (EM) game but, per IPDB records, was never put into production.

No rules, layout, or artwork details survive for Number Pool, and because it was never manufactured, no physical examples exist for collectors today. It remains known only as an entry in Gottlieb's internal design history from the mid-1950s, a period when the company was still one of the dominant EM manufacturers in the industry.
