HOW DID YOU KNOW? - Rules and Regulations

Once a month, Neatorama and Mental Floss present a 5-day trivia hunt called How Did You Know?

Starting on the last Tuesday of the month, we present four challenges, one per day.

The final puzzle is presented the following Monday at 8 pm ET, which gives you the weekend to work on any missing pieces to the previous four days' challenges.

The first person to e-mail in all the correct answers to all of the challenges and the final puzzle, including ALL of the questions presented in the final puzzle, is named the winner and gets his/her pick of any t-shirt from our store.

Five random, daily winners are also picked, one per day.

Winner gets: any item from the neatorama shop valued at $25 or less. The item must be in stock and you can't redeem the cash value of the item. Also, if you're item is only

valued at $19, you can't use the remaining $6 toward another purchase. However, shipping is on neatorama!

Each evening, at 8pm ET, we’ll be putting up a challenge loosely based on the day’s previous two challenges.

You won’t need to solve the first two to solve the third, but knowing the day’s theme might help you be the first to crack Level 3.

Regardless, if you solve the 8pm ET puzzle before 10pm ET, and leave the answer on the appropriate neatorama page that we specify, AND you also tell usin that comment

what you want from the neatoshop , you will qualify for the random drawing, which will happen shortly after 10pm ET that night.

Be sure to fan us over on our Facebook page to stay up-to-date with the latest challenges and rules.
