Due to the constraints with the numbers on a standard set of dominoes, the facts practised here are limited to elementary multiplication and division up to 3 x 2 = 6.
After some games, the students will realise the rules that apply to placing some dominoes. For example:

•  A “double” domino, such as ,  can only be joined to a single dot on a domino. For example:

•  Five-dot dominoes are difficult to match.

• Some combinations cannot be matched to anything. These are:

As an alternative game, the rules for joining can be adjusted to include all the operations. This would make it possible to join all dominoes to others. For example:
