A crown dealer has been spared immediate jail after admitting he conspired with punters to rig a gaming machine in their favour.

Casino croupier Gangyi Zhang, 36, took bribes from gamblers to manually override a roulette machine, costing the casino more than $60,000.

The County Court heard Zhang, of Pascoe Vale, was paid $6000 in secret commissions by one gambler, Deasy Widjaja, to ensure her number came up.

Prosecutor Dennis Smith said the experienced dealer discovered a fault in the Rapid Roulette machine, allowing a winning number to be fixed before the wheel was spun.

The electronic table game is similar to traditional roulette, but players sit at individual terminals and place bets on a touch screen.

Between October 2003 and January last year Zhang manipulated the machine eight times for Widjaja and others.

The court was told Crown surveillance cameras caught Zhang in the act and police arrested him in January last year.

Crown spokesman Gary O'Neill said the casino's video monitoring system was world-class.

"I don't know why people think they can beat what is one of the best security surveillance systems of any casino in the world," he said.

Zhang was yesterday given a 12-month wholly suspended sentence after pleading guilty to nine dishonesty charges, including seven counts of obtaining property by deception.

Judge Leslie Ross said Zhang had been motivated by greed.

The court heard Widjaja, 29, who pleaded guilty to three dishonesty counts, won $19,000 on the rigged machine.

The gambler, who came from Indonesia in 1995 as a student, was prepared to make restitution, her lawyer Adrian Kennedy said. Judge Ross ordered Widjaja be assessed for a community based order.
