released. In 1989 a version of Repton 3 featuring all expansion packs was also released for the BBC Micro's replacement, the 32-bit Acorn Archimedes. Its programmer, John Wallace, also produced a slightly expanded version of Repton 2 for the Acorn Archimedes which was released on the 1993 Play It Again Sam 2 compilation (which also included Zarch, Master Break and Arcpinball). None of these ports achieved the sales of the BBC originals. In the late 1990s, Superior sub-licensed the games to ProAction who released a number of RISC OS ports for the Acorn Archimedes and RiscPC. John Wallace created new ports of Repton, Repton 2 and Repton 3. ProAction also released Desktop Repton which includes the 3 games (including the expansion games for Repton 3). These games were built from scratch by Darren Salt, and developed to run in a multi tasking window on the desktop. There was also Desktop Repton Plus, with new PC graphics and extra levels included for Repton 1. There have been numerous ports of Repton 3, including a free version for Linux. Under the name Superior Interactive, the original publishers re-released versions of Repton 1 (2003), Repton 2 (2004) and Repton 3, including all of the expansion games (2005), for Microsoft Windows. They also released a large pack of new levels for all three modern Repton ports named Repton Spectacular in 2010. Also in 2010, iRepton was released for the Apple iPhone / iPod Touch (ESZ Consulting / Superior Interactive). This has retro and enhanced graphics and sounds and new screens. On 7 October 2014 iRepton 3 was released for the iPad and iPhone, featuring the same level of graphic enhancements as iRepton 1, which also had an overhaul at the same time. Clones A deliberate clone called Ripton, extremely faithful apart from different level design and several humorous digs at the original game, was written by Kenton Price and submitted to A&B Computing but the magazine never dared to publish it. It is, however, now available at BBC software Internet sites. There was also a PD clone for the ZX Spectrum called Riptoff, which included a level editor. It was developed by Rick O'Neill and Craig Hunter, and was released exclusively on a 1991 Your Sinclair covertape. Derivatives Because of Repton'''s ubiquity on the platform it became impossible not to compare to it any later commercial scrolling-map game for the BBC/Electron. Later puzzle-based games
