Black and White Cats is a puzzle in Professor Layton and the Last Specter.


You want to display your impressive collection of black and white cat paperweights on this 4x4 grid.

You must fill every space, and no row or column can have more than two same-colored cats next to each other.

The six cats currently must remain where they are. How can you fill in the rest of the grid?

Touch a space on the grid to place a cat, change its color, or remove it.

Anytime you spot two adjacent cats of the same color in a row or column, any space next to them in that row or column will need to be filled with a cat of the opposite color.

First, concentrate on the placement of the white cats.

You can only plance a total of four cat paperweights in any single row or column. Once you figure out where the white cats go, you can pretty much fill the remaining spaces with black cats.

A white cat must belong in the empty space between the two black cats in the column farthest to the right.

remember, when you have two cats of the same color next to each other in the middle of a row or column, you must place cats of the opposite color on either side of them. Continue placing paperweights according to these rules until the grid is filled in!

Put a white cat between the two black cats in the column farthest to the right.

Put white cats in the top and bottom spaces of the second column from the left.

Put a white cat between the two black cats in the second row from the bottom.

Think you can figure out the rest?



Too bad.

Start by looking at the paperweights that have already been placed on the grid.



There was no rule about having an uneven number of black cats and white cats!
