Jeremysr made a trivia game for the DS, which is supposed to work a lot like IRC Triviabots but with only one player. It gives you a hint by showing the answer with all the letters replaced by dots, and starts revealing more dots every time you get the question wrong.

The game comes with a questions file to put on the root of your card. It contains 10 000 questions from an IRC Triviabot.
