Awesome for trivia lovers

I’m a big fan of trivia and Big Brain makes it even more fun with daily quizzes AND best of all: winnings!! Categories are nice and varied and it’s fun coming up against old and new foes that you recognize. Makes me even more competitive! It’s a waaay better experience than that trivia app HQ that had the annoying host and way too much down time. Big Brain gets straight to the point.

What crap!

I am so glad I haven’t deposited money into this game. My very first practice game got stuck and made me completely miss one question and only gave me seconds for another question! How can I get the points to help me win this way?! I would have surely lost my money! There is nothing wrong with my internet connection as I am playing at home with my own WiFi. Now I am extremely unhappy that this app has my personal information because it requires scanning your driver’s license or ID to play and I have no way to remove this information. I was able to hide my email from them! No wonder there are hardly any players or reviews from this game debuting in December. I should have read the app information more clearly. BEWARE!!!

It’s legit, and it’s fun.

I’ve played a lot of trivia games online, and I’ve won playing a ton of them, from Total Trivia to Fleetwit. This compares favorably with the best of them. It’s tough to find a trivia game that actually pays out and doesn’t rely on nonsense. BigBrain has delivered so far. My fellow competitors are tough though! This ain’t a game for casuals. Bring your A game!
