You're close, but you forgot the shotgun and the fake gold coin.

We don't distinguish between what you're calling brain teasers and what you're calling puzzles, at my company at least.
Here's a good one. How many squares are on a chessboard?
Hmm,
- Squares of area 1: 64
- Squares of area 4: 49
- Squares of area 9: 36
- Squares of area 25: 25
- Squares of area 36: 9
- Squares of area 49: 4
- Squares of area 64: 1
- Squares in the chairs adjacent the board: 2
- Total: 190 (188 if you don't count the players as being "on" the board)

Clumsy of me -- I missed Squares of area 16 (of which there are 16).
Total is 204.

Yup. I quoted your answer so that you wouldn't try to be sneaky and edit your post. :-)
I wasn't sneaky and didn't edit my post because you quoted my answer....
Ahh, the trick was remembering that there were also two squares playing the game.

allegations of cheating or propensity to cheat should be kept inside the Cheating Forum and even then not levelled at named members...
To the 6,8,24,96,? problem, I wonder if my solution works too. 6 (*4-16)= 8 (*4-8) = 24 (*4 -0) = 96 (*4+8) =392. I'm going with 392, seems a more elegant answer.

There is no point arguing. Both the brain teasers (those you can't solve if you assume only the information that was given explicitely) and the puzzles are fun. Both of them are used in interviews for jobs that require strong communication skills and creativity.
By the way, the two puzzles I wrote above can be solved with no math. All that you need is an idea.
Theoreticalboy: you are correct.
And the lights and switches puzzle involved an idea, since it is impossible to solve it without that idea. If you can figure it out without using heating one of the bulbs up, let us know.
[deleted by me...again, who cares? Costelus' answer is good enough, though, even a virtual me wouldn't want to wait months.]

Actually I can solve it without using the heating. I turn one switch on and leave it on for a couple of months, until the bulb will surely burn. Then I turn that swithc off, turn on another switch and go into the room ...
If you can't go into the room to check out if the bulb is burnt out how the Hell would you know when to turn on another switch? Tell me how it's done without causing some physical clue that doesn't involve walking in the other room? Obviously the riddle included the heated bulb.

It's not even a difficult problem, the light bulb one. But it is seminal. RIP Steve Jobs.

It's difficult for one Genius to grasp.

Even if you don't get it, it's just a trick problem. The real test, especially if you don't get it, is if you can apply that type of thinking down the road. Thud first time you see the solution can be like looking in 3D for the first time. Just make sure that you look in all 3 dimensions in the future, and you'll be good.

Life is full of trick problems.
