ADDICTIVE. CHARMING. CHALLENGING. A RETRO PUZZLE SOLVING CLASSIC! Repton 3 is truly one of the greatest puzzle games of all time! Selling hundreds of thousands of copies since first released back in the 80's for the BBC B Microcomputer. In addition to the original Repton 3 levels from the BBC B Microcomputer, Sinclair ZX Spectrum, Acorn Archimedes and the Commodore C64, we have also included all the original levels from the spin off games too, including: - Repton Symphony - Repton Around the World - The Life of Repton - Repton Thru time - Repton’s Adventures - Reptology - Bonus So Repton 3 is really seven separate games in one! “A true retro masterpiece” "I wasted hours of my youth with this game and now I can do it all again! THE best game by far back in the day and still brilliant now, I'm sure it's mostly responsible for my fantastic problem solving skills!! Get it, you'll love it." "Fantastically addictive, once I started I couldn't stop playing, a brilliant app" ___________________________________ You control Repton the lizard, and your quest is to collect all of the diamonds from a series of underground caves before the allocated time runs out. Some of the diamonds are easy to take, but many are located behind fiendish traps involving rocks, eggs, monsters, keys, safes, spirits, cages, skulls, transporters, earth and fungus. In each cave you also need to collect a crown, kill the monsters, and cage the spirits before defusing the time bomb to complete the level. If you're a fan of logic puzzles, or just fancy a break from aimlessly wandering around shooting things then Repton 3 is for you! With enhanced graphics and sound, Repton 3 introduces this classic game to a new generation on the iPhone, iPad and iPod Touch. It is fun for all players, from children to seasoned puzzlers.
