When they say 'Black gold', everyone knows perfectly that people are talking about petroleum. Crude oil it is called in the financial markets, and just oil by some pros of the industry, but we'd better still call it black gold, as gold, i.e. cash, is the thing we're looking for when playing Online Slots, right?

When playing black gold themed slots, you may sometimes come across with the symbols that refer to oil production and refining: oil wells, rigs, offshore platforms, and plants. Crude oil is also used to produce petrol, so cars and are vehicles may also appear. However, the black gold is also a symbol of riches, as oil tycoons are all extremely rich, so symbols of luxury are those that will often accompany black gold themed slots, too.
