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.
The following graphics show a Domino puzzle in the Crossword Express
and a PNG graphic file produced by the program's print function, showing the complete puzzle solution.
See also a full size version of a PDF file
showing the solution.
The key features of the Crossword Express Domino Construction function are as follows:-
Fully automatic construction of puzzles. Puzzle sizes are determined by the domino set used in their construction.
This can range from a minimum of 0-0/3-3 up to a maximum of 0-0/9-9.
A multi-build function allows the construction of many puzzles (thousands if necessary) in a single operation.
- Puzzles can be printed in an unprecedented range of user controlled colors and formats.
Output can be sent direct to the printer or, if you install the appropriate software, it can be sent to a PDF file. The
recommended software for this purpose is Primo PDF which
you can download free from their website, although you might consider sending them a small donation if
you find their program useful. Mac users will be able to create a PDF file directly from the screen provided by
the printer driver.
Formatted output can also be exported from the Print screen to graphic files which conform to the BMP, GIF, JPG or PNG formats.
A fully interactive Solve function is available to allow you to solve the puzzles "on screen" without needing to print them.
