Repton is the ultimate thinking man's arcade game requiring dexterity to complete its arcade-style elements, and clear logical thinking to solve its strategic puzzles. The Pocket PC release is an official conversion of the 80's BBC Micro classic, which sold over 125,000 copies in the UK.
In essence, Repton traverses mazes retrieving treasure from cleverly-constructed traps of falling rocks whilst avoiding the fearsome monsters. However, it is impossible to explain the appeal of the game in words: you have to play it to understand!
