Okay, I admit it, I played with the phone as a kid. (Hey, this was long before the days of video games and 500 TV channels.) But I've always been interested in telephone trivia, and that's what led me to today's mentalfloss.com Brain Game Think Thursday challenge:

As of 2012, five different three-digit prefixes
are used in the United States to indicate
toll-free telephone numbers.

Name all five.

Here are the ANSWERS.

THE ANSWERS:

800, 855, 866, 877, 888.

Thanks for playing! Tomorrow, it's Free-for-all Friday.
