QToro is a game where short questions, hard and easy, are asked in relatively simple English.  The player is then given several choices from which to pick the correct answer, and scores points.

You can type in the subject you want the questions to cover.  The questions and answers are actually contributed by players, and after the correct answer is shown you are shown a link where, if you want, you can go to find out more information.

It’s a neat game, one where students can be both “consumers” and “producers” of questions.

I’ve sent an email to the site asking if they can make a way that players can just pick questions written by particular people.  That way, students can answer questions developed just by their peers.  I’ll post if and when they respond.

I’ve placed the link on my Intermediate English page under Word and Video Games.
