Six Rooms
- Kropki dots
- Odd and even cells
The brief
- Divide the grid into six 2x3 boxes. It must be determined whether these are horizontal or vertical.
- Fill the grid with the digits 1-6, so that digits don't repeat in a row, column, or box.
- The boxes are numbered 1-6, in reading order from top left to bottom right.
- The yellow frame in box N displays the sum of all the digits within that box that are orthogonally adjacent to the digit N within that box. Eg: the yellow frame in box 4 contains the sum of any digits within box 4 that are orthogonally adjacent to the 4 in box 4.
- For 2-digit totals, the yellow frame covers a horizontal domino and the total reads from left to right.
- Every box will have a yellow frame. Only four of these have been shown; the position of the other two are to be discovered.
- The grey circle contains an odd digit.
- The white dot connects two consecutive digits. (Not all possible white dots are shown.)
