"A world memory champion and a neuroscientist have joined forces to create a language-learning website called Memrise, which combines mnemonic tricks with a game to help users learn quickly and efficiently. Its carefully paced learning structure and competitive points system, the app's developers believe, make their site more effective than other language-learning tools. Memrise makes learning a game with virtual gardens that users must tend. As they do, they also earn points and thereby fight their way up a community-wide leaderboard."
