Cwizz is a 'Who wants to be a millionair'-style quiz application. It features several game modes (normal, hardcore (no answers given)), with various question types (normal, ordering, images) and a bunch of multiplayer options (fastest reaching of final stage, best average score, ...). You can play with your friends or against strangers. We are also working on an android version, which is working, besides Linux and Windows.
There are also jokers like the 50:50 joker.
