Strategy
The 0 can only be one combination, 000. This is typically the first domino to be filled in and crossed off. Depending on the size of the puzzle, you can do the same with the highest combination of numbers, whether it is 333, 444, 555, or 666. This will sometimes lead to solving (or partly solving) neighboring dominoes. For instance, if one side of the 18 (666) domino connects to a 7 domino then the solver knows that one side is a 6, therefore it must be the 016 domino. It takes more information to determine the orientation.
In general, finding neighboring dominoes with large differences in value will help solve the puzzle. As more dominoes are determined, the limiting of choices will make further solving easier, as well.
