Our good friends at Google run a daily puzzle challenge and asked us to help get them out to the geeky masses. Each day’s puzzle will task your googling skills a little more, leading you to Google mastery. Each morning at 12:01 a.m. Eastern time you’ll see a new puzzle, and the previous day’s answer (in invisitext) posted here.

SPOILER WARNING:
As a test, we’re going to leave the comments on so people can work together to find the answer. As such, if you want to figure it out all by yourself, DON’T READ THE COMMENTS!

Also, with the knowledge that because others may publish their answers before you do, if you want to be able to search for information without accidentally seeing the answer somewhere, you can use the Google-a-Day site’s search tool, which will automatically filter out published answers, to give you a spoiler-free experience.

And now, without further ado, we give you…

TODAY’S PUZZLE:

How many leagues is the drive from the current location of Queen Matilda’s Tapestry to the site of the battle it portrays?

YESTERDAY’S ANSWER (mouseover to see):

Search [Mary Queen of Scots cipher] and read to learn that her cipher was a simple substitution cypher that substitutes symbols for letters. Search [decrypt substitution cipher] and read to find that it was cracked using a method called frequency analysis, which depends on the frequency that a letter appears to determine which symbol stands for which letter.
