qua is a game like "Jeopardy!", but with a little bit different set of rules, more like "Своя игра". But it's a version to play in the web. I made it very hastily for my bachelor thesis.
Now qua is nearly unplayable, and the code is garbage. I intend to make the game properly in the future.
Besides the game, there is a package editor, where you may create packages with questions to play with.
