Braingle is a host of more than 20,000 brain teasers, trivia quizzes, games, and mentalrobics (aerobics for the brain). The games section is comprised of popular games like chess, checkers, sudoku, and common word games. The Mentalrobics section of Braingle is what makes it worth mentioning. Mentalrobics includes memory tests, flashcards, and vocabulary building activities. The vocabulary builder activities require users to register for a free Braingle account. To help users practice more effectively the Braingle vocabulary builder tracks the words users know and the ones they don’t.

Thanks to Michael Zimmer for sharing Braingle on his excellent blog.

Applications for Education
Braingle could be a good resource for students to use to practice vocabulary words. The other Braingle activities could be useful for educational fun during those few minutes of downtime that teachers sometimes find in the course of a day.
