Straperlo or Stra-Perlo was the brand of a fraudulent electric roulette game, promoted by Strauss and Perlowitz.In 1935 during the Second Spanish Republic, they tried to introduce the Stra-Perlo in the San Sebastián and Formentor casinos in Spain. Corruption connected with the prohibition of the game reached the nephew of Alejandro Lerroux and caused the downfall of his Radical Party. The political centre was abandoned and the Spanish public polarized, contributing to the Spanish Civil War.
After the war, estraperlo acquired the meaning of black market, the illegal trade of ration items.
