Fun Trivia - The World's Largest Trivia Site

Quite a lot of trivia gurus on this site.

I have been on FunTrivia since around May of 2013. There are some incredibly fast and accurate players on there. And some very talented Quiz writers.

Some other Talk of the Villagers like Zen Rocks were or are still on there.

Some of the really good players can get 10 out of 10 questions correct in 10 seconds.

Global Challenge 48 just started yesterday afternoon. You can compete against some of quickest and most accurate online trivia fanatics in the world on there. I wonder if Ken Jennings is on there? You will have to get in soon though as otherwise you would have little chance of catching up with the leaders of the pack.

I created a username and password. I logged on. I played a few games. Took a bit to find games, the early 1990's format of their webpages is chock full of crap to wade through to find what I wanted to play. After 3 or 4 games I got bored. Haven't logged back in since. Still getting their spam junk email though.

It does take commitment and practice to get really good in the various competitions on FunTrivia. Some players seem to be on much of the day and night. You can buy a Gold Membership and it cuts way down on the ads. If memory serves it is $48 a year or $24 for six months.
