Lewis was one of the top players in the world during the first decade of “Modern Backgammon” 1964- 1974. Lewis Deyong transitioned into perhaps the best promoter, organizer, director, and auctioneer the backgammon world has ever seen. As the auctioneer in Monte Carlo, Lewis set a record of raising $256,000 (well over $1,000,000 at 2023 value.)
Among his finest masterpieces were the World Championships (first on Paradise Island, Bahamas, then in Monte Carlo), the U.S. Black & White Scotch Circuit of tournaments, and the $10,000 EF Pro-Am tournaments, which he ran for ten years, starting at the Ocean Club, Paradise Island, Bahamas, then Turnberry Isle, Florida, finally moving to Las Vegas.
