Think this is a bit easier than my last one - How many squares are there on a standard 8 x 8 chessboard?

204 squares :redface:

patcooke · Jul 12, 2011

Well done! - for those who would like an explanation:

There are 8 x 8 individual squares = 64
There are 7 x 7 (2x2) squares = 49
There are 6 x 6 (3x3) squares = 36
There are 5 x 5 (4x4) squares = 25
There are 4 x 4 (5x5) squares = 16
There are 3 x 3 (6x6) squares = 9
There are 2 x 2 (7x7) squares = 4
There is 1 x 1 (8x8) squares = 1

So the total = 64+49+36+25+16+9+4+1 = 204

Next?

yes it is...your turn :ahaha:

Are you serious? :ahaha:

Old one, best one I could come up with at the moment lol.
There's a room. In the centre of this room is a table. On the floor there is shattered glass and water everywhere. The window is open and the curtains are billowing. Jack and Jill are dead on the floor. How did this happen?

patcooke · Jul 13, 2011

Yep - nearly as old as me! The glass is from a shattered fish bowl - Jack and Jill were two fish in the bowl.

A lateral thinking puzzle - The timepiece that has the fewest number of moving parts is the sundial. Which timepiece has the greatest number of moving parts?

alfred01 · Jul 14, 2011

The nuclear world clock?

patcooke · Jul 14, 2011

A worthy answer - if we count electrons as individual moving parts but the answer I had in mind is more mundane and the parts more tangible . . .

alfred01 · Jul 14, 2011

A Cuckoo clock?

beeaitch · Jul 15, 2011

The universe?

patcooke · Jul 15, 2011

Another inspired answer but we're looking for a device which is designed solely and specifically for measuring the passage of time - (quite a mundane and old fashioned device).

Elmer · Jul 15, 2011

Hourglass? a.k.a egg timer?

patcooke · Jul 16, 2011

That's the one I had in mind - well done (I hadn't imagined the number of intelligent possible answers which have been submitted!).

beeaitch · Jul 17, 2011

Your turn Elmer

I've been teasing my brain trying to think of a Brain Teaser!!

The only one I can think of at the moment is relatively easy but caused 3 hours of debate / argument in my local one Sunday lunchtime.

If a hundred horses eat a hundred bales of hay in a hundred days. How many bales of hay will ten horses eat in ten days?
