I've made some JLPT vocabulary sets on Quizlet which can be used in the HTML5 games on this site and the PhraseBot app.
Try out the CrossBots game shown below right now - it's HTML5 so you can play from your phone, no app needed! To play, you take turns against the other robot, matching words from the 2-layered grid to clear a vertical path before he clears a horizontal path.
*The data is from the http://www.tanos.co.uk/jlpt site which has long provided many excellent resources for studying Japanese, and especially for the JLPT in the absence of official lists.
