A TATAMI puzzle consists of a square grid which has been covered with rectangular tiles which are either 3, 4 or 5 cells in area.
Any given puzzle will be fully covered using tiles of only one of these sizes. To solve such a puzzle, the solver must place numbers
from 1 up to the numerical size of the tile into the puzzle cells so that the following three rules are met:-
- The numbers within a tile must all be different.
- Horizontally or Vertically adjacent puzzle cells must not contain the same number.
- Each row and column of the puzzle must contain the same number of appearances of each number.
Some of the puzzle cells will have a number already inserted to get you started.
The following graphics show a Tatami puzzle in the Magnum Opus
and a PNG graphic file produced by the program's print function, showing the complete puzzle solution.
