HQ Trivia is a popular smart phone game where you answer questions for cash with a live host every day at 8 PM, also at 2 PM on weekdays. The day’s prize varies from day-to-day, but there is almost always cash there, from what I can tell. You also have a leaderboard to rank-up on, a way to invite your friends, and a live chat during games.
It has mixed reviews, and you either love it or you hate it. But regardless of where you stand on it, it’s now available on Android. The game is now marked as “Unreleased” and “may be unstable” so be careful when you are playing, as it may have glitches.
