of comparison, the U.S. State of Nevada, which legalised gaming including slots several decades before N.S.W., had 190,135 slots operating. Revenue from gaming machines in pubs and clubs accounts for more than half of the $4 billion in gambling revenue collected by state governments in fiscal year 2002–03. In Queensland, gaming machines in pubs and clubs must provide a return rate of 85%, while machines located in casinos must provide a return rate of 90%. Most other states have similar provisions. In Victoria, gaming machines must provide a minimum return rate of 87% (including jackpot contribution), including machines in Crown Casino. As of December 1, 2007, Victoria banned gaming machines that accepted $100 notes; all gaming machines made since 2003 comply with this rule. This new law also banned machines with an automatic play option. One exception exists in Crown Casino for any player with a VIP loyalty card: they can still insert $100 notes and use an autoplay feature (whereby the machine will automatically play until credit is exhausted or the player intervenes). All gaming machines in Victoria have an information screen accessible to the user by pressing the "i key" button, showing the game rules, paytable, return to player percentage, and the top and bottom five combinations with their odds. These combinations are stated to be played on a minimum bet (usually 1 credit per line, with 1 line or reel played, although some newer machines do not have an option to play 1 line; some machines may only allow maximum lines to be played), excluding feature wins. Western Australia has the most restrictive regulations on electronic gaming machines in general, with the Crown Perth casino resort being the only venue allowed to operate them, and banning slot machines with spinning reels entirely. This policy had an extensive political history, reaffirmed by the 1974 Royal Commission into Gambling: While Western Australian gaming machines are similar to the other states', they do not have spinning reels. Therefore, different animations are used in place of the spinning reels in order to display each game result.
