This is a HTML and jQuery based Jeopardy implementation. The mouse is only needed for selecting a tile, everything else is controlled using keyboard commands:
1...9select player (buzz)0reset player (undo buzzing)+right question was given, add points for current player-wrong question was given, substract points from current playerashow questionnnobody answeredxhide clue (after accidently clicking it)mplay think music (requires include/think-music.mp3, not included in this repo)sstop musicddemo mode ("tile runner")F1...F12orllock input
jeopardy.html reads the board from JSON files (board.json by default, but you can use jeopardy.html?myboard.json to use a different file). If you include images, I'd recommend not to specify image dimensions and use CSS max-width/max-height instead.
It's possible to add one or more "daily doubles", see Category1 for 500 in board.json for an example. (Note that the player who picks a daily double needs to buzz nevertheless.)
print-jeopardy.html can generate a printable cheat sheet from the JSON files for the game host.
Note that this implementation expects the game host to provide sane input. It has some safety nets for obvious errors, but not for everything.
Also note that nowadays browsers refuse to load JSON files if you open the page via file://. You'll need to set up a basic webserver so that you can access the Jeopardy board and the JSON files over http or https.

It is based on Ryan McDevitt's JavaScript Jeopardy and uses jQuery.
