Video game fans have been invited to collaborate – and compete – in designing a game.
The 48-hour Scottish Game Jam takes place at the Pleasance later this month, with events also being held in Glasgow and Dundee.
The competition runs from January 25 to 27 to coincide with an international event taking place at the same time.
Competitors are allowed to sleep during the marathon. To enter, visit www.scottishgamesjam.com/jam2013.
