DOMINO PUZZLES

A DOMINO puzzle consists of a rectangular grid, with each cell of the grid occupied by a single digit number.

The grid represents a set of domino pieces laid out in a rectangular array.

For example, if you use a "standard" domino set having pieces ranging from 0-0 spots to 6-6 spots, then the rectangle will be 8 cells across and 7 cells down.
The puzzles can be made in various sizes, depending on the size of the domino set you use.

To solve such a puzzle, it is necessary to outline pairs of adjacent numbers in such a way that every piece of the domino set is revealed.
Each puzzle has a unique solution, and can be solved without recourse to guesswork.
