Australian-listed Crown Resorts Ltd. has entered the court room with full arms swinging as it fends off allegations that its poker machines are designed to cause gambling addiction.

The Sydney Morning Herald reported Crown Resorts went on the offensive at the start of the hearing of a landmark lawsuit filed against the casino operator and game technology provider Aristocrat, poking holes in the arguments raised by problem gambler Shonica Guy.

Guy earlier claimed that the popular Dolphin Treasure pokie machines in Crown casinos were designed to entrap users like her. She wanted the court to declare the game to be unlawful.

Guy’s claim is based on the Dolphin Treasure machines having symbols that are unevenly distributed across its five reels. The final reel contains fewer winning symbols in order to make it harder for punters to win.
