[cornettracing80]

wow cool!
please let us know what you got!

[HotRodLincoln]

That's because I don't know what it is yet. I just got a note saying I was getting a little something extra in the box when I get my Revomaze Very unexpected!

Congrats walther, i figure you're getting a stand, or a special stand. Either way, let us know when you know.

Brain Teaser 2.1

I thought a hole had nothing in it...

So my answer is ... No dirt...

I got the same answer, didn't realise I should just post it, I PMed HotRodLincoln instead.
Anyway, has anyone else got another one?

[walther]

This might be too devious

More strange math:

Nine - One = 8
Nine - Four = 1
FortyTwo - Fourteen = 37
Twenty - Twelve = ?

Okay, so that was a very simple one to start with. How about this for those less math inclined:

Brain Teaser 2.3
Three intelligent soldiers are being held at prisoner at a P.O.W. camp. As the camp begins to run out of food, a challenge is given. The three soldiers are securely blindfolded and then had their foreheads marked with either a green or a blue mark on their head. If anyone can guess what color mark they have, then the group will be released. However, a wrong guess will result in the death of all three soldiers. The soldiers are required to keep their hands in their pockets unless they see a green mark, in which they must raise their hands. The blindfolds are removed and all three men raise their hands. One eventually speaks up and says, "I have a green dot."

How did he know?

Used to know the answer to this.. Many variations on this one.

Working on walther's at the moment. But I'm really waiting for ReVoMaster's (although I'm not aloud to win it! I'm not too disheartened by that though... )

[walther]

How did he know?

Assume binary
1 2 3 1 2 3
------ ------
0 0 0 x x x - Not possible No Hands raised
0 0 1 x - Not possible 1 hand not raised
0 1 0 x - Not possible 1 hand not raised
1 0 0 x - Not possible 1 hand not raised
0 1 1 - Not enough Info for prisoner 1. 2&3 can see 1 Blue Mark
1 0 1 - Not enough Info for prisoner 2. 1&3 can see 1 Blue Mark
1 1 0 - Not enough Info for prisoner 3. 1&2 can see 1 Blue Mark
1 1 1 - Only logical solution all 3 have a green dot on their head

or something along those lines....

[HotRodLincoln]

you've got the basics

[walther]

What no guesses??

And the Riddle #3 prize is a Green Puzzle I can't wait to see it!!!
