Zeljko Ranogajec was born in Hobart Australia on the 22 May 1961 to Croatian immigrants. He is a professional gambler and Entrepreneur, also known as John Wilson. He studied finance, tax and banking at the University of Tasmania before becoming a professional gambler. It was at this University that his interest in gambling and more specifically, card counting started.

He tested out his newly learnt skills at the Wrest Point Casino, and this is where he met his future wife Shelley Wilson, who subsequently became his business partner.

Zeljko and his wife then moved to New South Wales where he initially continued his studies, but then dropped out to concentrate on gambling fulltime.

Gambling at Australian Casinos

Zeljko initially started gambling at the well-known casinos in Australia like Wrestpoint Casino and Jupiters Casino on the Gold Coast.

He was subsequently banned from all of the Australian casinos, so started visiting the Las Vegas Casinos.

However, He had problems getting his winnings back to Australia, so he had to hide his winnings and duck and dive the authorities. He was soon banned from the casinos in Las Vegas as well.

Advantage Play

Zeljko was always looking at different advantage play in other areas and branched out into Keno and Horse Racing where he continued to rack up the winnings.
On average, he earned $1billion per annum.

In 2011 Zeljko was inducted into the Blackjack Hall of Fame alongside many other well-known gamblers like Bill Benter, Don Johnson and Stanford Wong.


Zeljko Ranogajev still gambles at sites like Betfair but keeps a low profile and leads a reclusive lifestyle. In 2019 and 2020 he appeared in the Australian Financial Review rich list with an estimated fortune of 600 million Australian Dollars.

He currently lives in Hyde Park, Knightsbridge, London.

Don Johnson

Don Johnson Don Johnson

Don Johnson is a professional Blackjack player who was born in Salem, Oregon in 1962. During his younger years, he was involved with horses and trained to be a jockey.

When he was 30 years old, he was hired to be the Manager of the Philadelphia Park Racetrack. He also managed other racetracks and was a regulator in different states.

During this time, he developed a computer-assisted wagering strategy for the horse race betting industry and started a Company called Heritage Development which specialized in computer-assisted wagering programs.

However, despite his horse racing knowledge and skills, his passion was the game of Blackjack. Furthermore, he also developed a Blackjack strategy by using his PhD in Mathematics and subsequently became a wealthy man and a high roller.

15 Million Won at Atlantic City Casinos

In 2010 Atlantic City Casinos were suffering from the Financial crash of 2008, so they tried to lure various High Rollers to play their high stakes games. ( 80% of casinos profits are from high roller players )

Don Johnson was one of those invited to play at a Blackjack game with high stakes. However, he had certain conditions he laid down before accepting. He wanted various changes to the game such as a 20% cashback on losses, re-split of Aces, six decks of cards, and the dealer must stick on a soft 17.

To their detriment, the casinos agreed to this condition. Johnson landed up winning $6 Million at Tropicana Casino, $5 Million at Borgata and $4 Million at Caesars Casino. Caesars Casino banned him entirely, and the other two casinos allowed him to play under specific conditions and limits.

Where is Don Johnson now?

Don Johnson still frequents Las Vegas Casinos, but he says many won’t allow him to play Blackjack, so he spends more time playing on the horses instead.
