Gone are the Pokemon Go crowds, the kids in Australian suburbia are now hunting special rocks.
Australian mother of two, Alana Stevenson, kick-started a free game that is encouraging children to play outdoors.
The Byford mum says her two boys, aged 10 and three, have not asked for their iPad since she started the WA Rocks movement.
Inspired by a game in New Zealand, the 31-year-old has been uploading photos online of hand-painted rocks and where they are hidden.
The idea is that gamers can locate them, re-hide the colourful rocks and even make their own treasure rock hunt for others. There are groups springing up all over Western Australia.
