Historically, an oracle could be a person through whom it was believed a deity could speak or someone who it was said could bestow prophetic advice. A classic example is ancient Greece's Oracle of Delphi, where the priestess would go into a trance and speak messages that were believed to be from the god Apollo. These messages were often ambiguous and cryptic, leaving space for interpretation. Less ambiguous is the Pragmatic Play title Oracle of Gold, a cluster pays slot which enriches its gameplay with wild multipliers, as well as a rising total multiplier available during its free spins bonus round.
