It is a game of questions and answers in the most varied categories, as well as the Questioned - which was very successful among Brazilians. The big advantage is that the HQ Trivia rewards the winners with real money. To win the prize, usually divided among all winners, simply answer 12 questions quickly and without missing a beat. You do not have to pay anything to play, and if your friends enter through your link, you can earn "lives" that will save you if you miss a question.
The only problem is that the game is aimed at the American public, so you will need a good knowledge of English to do well in the rounds, which always happen at certain times. The premium varies and can reach up to $ 2,500 per day, with values distributed via PayPal.
I never managed to get any cash on it nor know anyone who had.
