Nevada's 151,000 slot machines are, by law, purely games of chance, meaning everyone has the same chance of winning.

The US state of Nevada is drawing up plans to introduce games that pay out based on skill instead of chance.

The games will be targeted at a younger audience more used to console and app gaming than slot machines.

Because of this, the Association of Gaming Equipment Manufacturers pushed for a Nevada law - which was passed unanimously earlier this year - that directs regulators to craft rules for new kinds of skill-based games.

According to Associated Press, game developers, slot machine makers, lawmakers and regulators estimate that new skill-based games will offer a boost to Nevada's casinos, which have seen gambling revenue slump from nearly $12.9bn in 2007 to about $11bn in 2014, with slot proceeds alone plunging 20 per cent.

Greg Giuffria is developing a line of console video games that allow betting. He said: “The next wave of people aren't going to stand there and play slots.

“The industry has to change or disappear.”
