Not sure if any of you followed the Da Vince Code Quest thing which Google ran last month. Now, Google has Puzzlemaster Wei-Hwa posting a challenge question each day (you have to use the 'Personalised' Google Home Page). I'll post them here, and you guys can solve them.

First one; I think we've had this countless times before:

**May 26th, 2006**: While we're still getting some fancier stuff ready behind the scenes, I thought this would be a good place to put some neo-classic puzzles. Hope you like this one:

Using the numbers 3, 3, 8, 8 (in any order), make a mathematical expression that equals 24. You can use only addition, subtraction, multiplication, and division (and parentheses), but in any order you wish. Note that you have to use all four numbers; otherwise 3 times 8 would be valid -- and that wouldn't be much of a puzzle, would it?

**June 2nd, 2006:** If a tree falls in the woods because of a wound, then what little object will not hear the sound? Answer: a deaf leaf.

A Why Me Rhyme is a pair of words that look like they should rhyme (after all, only their first letter is different), but don't really. For example, depending on the colorist, Etrigan could be considered a lemon demon. See if you can figure out these twelve Why Me Rhymes from their descriptions:

a) What is heard when your little girl is having fun

b) A disgustingly dirty sticker

c) A siesta for weirdos

d) A friendly rejection

e) Lists of all sorts of animals to be eaten

f) An unrefined crucifix

g) A type of bar bet, maybe?

h) Makes a news agency irrelevant

i) Stamps that someone refuses to return

j) Makes contact with feminine hygiene products

k) A price reduction given only to certain noblemen

l) Newer style of patio furniture

Only one I have so far:

I don't know the answers [ooh, but I've found that I can check them and get back a 'wrong' or 'right'], but that sounds right, Rod [and actually, yes it is]. Good job!

k) viscount discount

Too good, c0de! What a great first post. Looks like it took you all of seven minutes.

And well done too, Rod. Close, but no cigar.

And I had figured out the siesta one too - just hadn't posted it

So, is that it from c0de? One brilliant post, then disappears into the night?

**June 9th, 2006:** The Google US Puzzle Championship is next Saturday, June 16th. It's used to select the US Puzzle Team, but puzzle-lovers of all sorts should find something interesting in the puzzles. Let's have a big "G" (for Google):

Here's a puzzle based on Erich Friedman's "Distance," from the 2003 Google U.S. Puzzle Championship. Label 14 of the circles above with different numbers from 1 to 14, such that the distance between 1 and 2 is less than the distance between 2 and 3, and so on. Four circles should remain empty.

**June 15th, 2006**: It's hard not to be tempted by parody. It will probably be a while until we can actually get online collaboration, but I was able to come up with some interesting variants of Minesweeper. You can try them out (as well as the standard game) this week:

Your puzzle, of course, is to figure out what the rules to the variants are. Shouldn't be too hard, although there are quite a few secrets to discover!

**June 23rd, 2006:** Three weeks ago I was playing in The Game. One particular challenge was a timed maze (written by Stanford students Rachel Weinstein and Frank Losasso) that we had to play on a dance pad. It took my team surprisingly long, probably because we hadn't slept for 20 hours and we had failed to notice an important rule...

Now, you can share a little bit of that experience. Start clicking and see if you can figure out the rules and solve the maze. When you win, you won't be able to reset the puzzle any more -- that's deliberate.
