Xanthos is right. Your solution is utterly false.
See?
Virak is very clever. No funny voices needed.
Fetofs also sent the right answer to my puzzle by PM, well done Fetofs!

Just to illustrate via an example for anyone who disagrees. Say the hat colors are from back to front.

The back guy sees 5 white hats so he says his hat is black. This is wrong so he loses out. Can't be helped. The second guy sees 4 white hats and realising that 4 is even think well the only way the guy behind me could see an odd number of white hats is if I have a white hat.
The 3rd guy says number 2 has a white hat and their are an odd number of white hats between numbers 2 and front. I see 4 white hats so counting number 2 I know of 5 white hats, gee I must have a black hat.(If I had a white hat then thier would be 6 white hats and 6 is even). Etc
Iamatiger thank for the generalisation.
