It's Jeopardy Labs and is a thousand times easier and more efficient than trying to build Jeopardy with Power Point.
You can choose "Quick Build" and start building your game right away. It's an easy click and type process. When you are finished, just click "Save."
HOT TIP: After saving, J. Labs will take you to a screen that gives you the URL to play and a URL to edit your new board. COPY, PASTE, and SAVE the two addresses somewhere. This is the only way you will be able to get back to your game to play or edit. Check out screen shot below.
Like many other online tools, you can browse its gallery of games built by other teachers. Don't reinvent the wheel - make an existing wheel better.
Let me know how it goes if you give it a try!
