The illustration explains itself. The eighteen dominoes are arranged so as to
form the required square, and it will be found that in no column or row is a
number repeated. There are, of course, many other ways of doing it.
- A DOMINO STAR
The illustration shows a correct solution. The dominoes are placed together
according to the ordinary rule, the pips in every ray sum to 21, and the
central numbers are 1,2,3,4,5,6, and two blanks.
