Edited post: for anyone who read the earlier post about round 292 - it is definitely possible, so I've deleted the earlier post where I said I hadn't yet got a solution (as I did finally find one!)

First in with perfect answers to rounds 292 and 293 is snookersfun. Congratulations! For round 293 (the 12x12 chessboard), snookersfun has found solutions for two different sizes for the yellow (and hence every other colour).
Congratulations to semih too for an almost perfect answer above - just needs to add the colours and it will be perfect.

Nice paints, April
Now pour them on the chessboard
We'll leave rounds 292 and 293 open, as I think a couple of people may still be working on them. But, so as not to delay, another chessboard question! ....
Round 294 That's odd
So... we've had boards of 8x8, 10x10 and 12x12! All even (i.e. even number of rows).
The Nugget has got a bit bored with every board so far being even - in fact, he found it a bit odd that they were all even - so, to even things out, he decides to stop colouring in an even board and look for an odd board, so he won't get bored with the next board. How odd!
He has also found that using the six colours from snooker every time is making him loopy, so he decides that from now on, different numbers of colours can be used - not necessarily six.
As always, the first two shapes can be any size. After that, it must be possible to make every shape by sticking together the two previous shapes. Rotating or flipping the shapes over (reflecting them) is permitted, just as before.
He gets out lots of paints but, so there won't be any monkey business, he pops around to my house, as he often does, and asks my pet apes to help him out.
First, he asks Charlie to colour in the smallest possible square board he can, with an odd number of rows. The only thing that he stipulates is that Charlie must use at least 3 colours, otherwise it would be too easy!
Then, the Nugget asks Gordon to colour in a square board with an odd number of rows, as many rows as Gordon likes, but Gordon must use exactly 147 colours!
What possible answers do Charlie and Gordon, each being very smart and able to solve any puzzle, give?Last edited by davis_greatest; 29 December 2007, 02:20 PM."If anybody can knock these three balls in, this man can."

Round 293 update
Meanwhile, abextra has provided two different possible colourings for round 293, the 12x12 chessboard! Well done! We'll leave it open a little longer, before inviting the colourings to come on the thread.

...and coming back, I found a perfect solution to the very hard spoon question (R.290) from Monique now. Very well done!

... and snookersfun meanwhile has sent a correct answer to round 294! Well done!
That means that both abextra and snookersfun have solved all the snooker chessboard questions so far (rounds 291 to 294) and Monique has done round 291 so far (was obviously too busy with those crazy spoons!)
So (and in response to a request for more time!), we'll leave rounds 292 to 294 open until 9a.m. GMT Thursday, 3 January 2008 or until the next person solves them, whichever is the sooner.
Anyone wanting to answer before that time, please post answers directly on the thread. After that, or earlier if anyone else has posted correct answers before then, would abextra and snookersfun please post their answers up here.
One last snooker chessboard (for now) from the Nugget - and then he or I will think of something else ....
Round 295 - A big outdoor chessboard
Davis has now found, on his Brentwood estate, a rather large patch of land that he would like to be coloured in, using the six snooker colours, just as in rounds 291 to 293.
This time, the patch is a square of 1470 rows (i.e. a 1470 x 1470 "chessboard")!
This being quite a challenge, he comes to Oliver, who can solve any puzzle (if it is possible to do so) and Steve asks Oliver whether he can colour it.
What is Oliver's response - "yes" or "no"? (And you must give an explanation - either a proof that it can be done or a proof that it cannot!)"If anybody can knock these three balls in, this man can."

R293 ...
R293.3-10.bmp
Here is a solution (if I'm not confused once again ...) with 3 yellows and 10 greens.
Now looking for one with 6 yellows and 8 greens.

Congratulations Monique! Nice pictures
Everyone has got quite different pictures - abextra and snookersfun, please would you put yours up too.
Below was my drawing for round 293, the 12x12 chessboard.
Round 294 now closed
I have received answers by private message to round 294 from snookersfun, abextra and Monique, so we'll close that round too. Please would you put up your drawings for the smallest possible odd chessboard that Charlie found, using 4 colours.
As described in a number of different ways in the answers I received, it is impossible for Gordon to colour in an odd number chessboard using 147 colours. This is because if the number of colours is divisible by 3, as 147 is, the number of squares coloured would always be even, whereas an odd chessboard has an odd number of squares. The 1st & 2nd shape combined equal the 3rd shape, the 4th and 5th combined equal the 6th, the 7th and 8th combined equal the 9th etc. - so an even number of squares is coloured after every 3rd colour, no matter what the size of the initial shapes."If anybody can knock these three balls in, this man can."
