I've tried a few online jeopardy simulators before, but have always just ended up going back to hunching over a laptop together with my friends on j-archive.

This looks much more convincing than ones I've seen before, especially the fact that you can just play prior game boards without any fuss. I'll have to give it a try with my friends, but so far gameplay feels smooth and the jeopardy-like accents are a good touch.
