BrainWhirl is a flashcard memorization game (see http://en.wikipedia.org/wiki/Flashcards for more information about this method). It would like to be a funny way to learn boring list of various things, but can also be used as a purposeless game.
You can either choose an existing game, browse online games or build your own and submit it for a next release of brainwhirl.
Game included : Indian alphabet, Roman numbers, mental calculus, elements
Please try devawhirl free software before to buy. The game experience is the same. Brainwhirl extends game sets about various e-learning subjects (vocabulary lists, alphabets, science...)
