Nick Petrovski found a foolproof way to make thousands of dollars from poker machines. Unfortunately, it wasn't legal.The 25-year-old appeared in Wollongong Local Court yesterday charged with six counts of fraudulently obtaining money in connection with a gaming machine and seven counts of interfering with a machine's operation.Petrovski, of Gilgandra St, Lake Heights, pleaded guilty to all charges.Over the course of three months last year, he and up to two others managed to accumulate $5690 by tilting poker machines in such a way that they paid out cash without losing the credits accumulated on the screen.Petrovski and a second person were seen on security camera footage at Macksville Ex-Services Club about 7.20pm on September 11 last year.They tilted the machine and later in the night asked for a $950 payout. It was handed over without question.It was only when an audit at the club revealed a $960 discrepancy that the CCTV footage was checked and Petrovski identified, but by that time he was long gone.On November 28, Petrovski and a woman pulled the same scam at Catalina Country Club in Batemans Bay.Petrovski braced himself against a pillar near a poker machine and pushed the machine to an angle and an object was placed under it.During the course of the evening, the pair received four payouts from the club totalling $2181.90.The next day they did the same thing at the Cooma Ex-Services Club, netting $2550 in the process.At the Merimbula-Imlay Bowling Club on December 11, Petrovski was not so lucky.He had used a number of $1 coins to hold a machine at a tilt and used a plastic sheet to force the coins put into the machine to fall out while the credit remained in the machine.He had accumulated $869 but before he got a chance to collect the winnings, a staff member noticed him and his accomplice acting suspiciously and the pair fled the club empty-handed.Petrovski is due back in court on April 29.
