Definition
Zeljko Ranogajec (born 22 May 1961) is an Australian businessman and professional gambler renowned for his large‑scale wagering activities in horse racing, blackjack, keno and other forms of advantage gambling. He is frequently cited as one of the most successful and secretive bettors in the world.
Overview
Ranogajec was born in Hobart, Tasmania, to a family of Croatian immigrants. He began his gambling career while studying commerce and law, initially employing card‑counting techniques at the Wrest Point Casino in Hobart. Over time, he expanded into multiple gambling domains, developing sophisticated betting systems and establishing a network of spotters, analysts, and administrators to support his operations.
His activities have led to bans from several Australian and international casinos, earning him the nickname “The Joker.” In 2011, he was inducted into the Blackjack Hall of Fame. In recent years he has been based in Europe, particularly the United Kingdom and the Isle of Man, and has acted as a consultant for companies involved in horse‑racing betting syndicates.
Etymology / Origin
The given name “Zeljko” is of Slavic origin, common among Croatians, and means “desire” or “wish.” The surname “Ranogajec” is also of Croatian heritage. Ranogajec’s family emigrated to Australia in the early 1950s, which explains the combination of a Slavic name with an Australian upbringing.
