... by: Jeroen W, The NetherlandsAt first, great pzzl! I can see many variations to come!
Second, pls check str8ts @ newspaper Trouw of today 01-11-09 http://www.trouw.nl/ontspanning/article1930461.ece/Straigth.html
I'm not able to solve this str8ts because if u look at column 6 the're is an eight white field compartment and one black. Since there is a 1 in the white compartment the highest number to fill out is 8. This puts a 9 in the only black compartment A6. But, look at A9, there is allready a 9 as a clue.
Pls advise ..

Don't try and fill in the black cells! They may or may not resolve to one number but itís a mistake to try and fill them. On the player you cannot edit that cell. The puzzle does not require unqiue numbers or any number in black cells - other than the given clues - try not to think of Sudoku. The only correspondance with sudoku is unique in rows and columns - but in white cells only.
