Repton is a computer game originally developed by 15-year-old Briton Tim Tyler for the BBC Micro and Acorn Electron and released by Superior Software in 1985. The game spawned a series of follow up games which were released throughout the 1980s. The series sold around 125,000 copies between 1985 and 1990 with Repton 2 selling 35,000 itself. The games have since been remade for numerous more modern systems, most recently as iRepton for the Apple iPhone / iPod Touch in 2010.
