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.
Solving a TATAMI puzzle is controlled by means of a cursor cell which can be moved around the puzzle using the arrow buttons, or by clicking with the mouse.
Any legal digit typed on the keyboard will be placed into the cursor cell. You can also complete the solution by removing candidate numbers from the cells
by pointing and clicking with the mouse. When the last one is removed from a cell, it becomes the solution for that cell.
