Solving Techniques
The techniques for solving the puzzles are simple. .I like these puzzles very much and I have listed some of the rules I use when I solve these puzzles. Please send your comments to pete_j_j@yahoo.com
Easy Rules
A. Only place for a piece
In this domino Puzzle, there is only one place in which the Domino 0– 0 can be placed.( the cells that are shaded).
B. When there is only one neighbor for a cell, then it must make a Domino with its only neighbor.
In this example the cell (2) in the upper right corner of the grid has only one neighbor. So the cell in the upper right corner , and its only neighbor must make a domino piece 2 - 2.
C. Divide the cells when the Domino is already found
The piece 1 – 2 is already found (see third row 4 th and 5th cells). So the 2 and 1 in the highlighted cells cannot form a domino piece.
Contradiction Logic
When you cannot solve a domino puzzle with the easy rules you have to make some assumption ( what - if Logic) and Disprove the assumption.
The assumption is disproved when the following contradictions are met.
An odd area is created
No Domino Piece is possible in cell
No place to put a domino piece in the grid.
When you are sure that the domino puzzle is unique, then you can use the logic that the puzzle cannot have two solutions.
