No. XVI.—DOMINO PATIENCE
The problem is to construct, with all the twenty-eight stones, a domino pyramid of seven stages, starting with a single stone, and adding one stone on each successive stage.
The stones must be so arranged that the number of pips in any row or column are in all cases exactly three times the number of half-dominoes of which that line or column is composed. There are many solutions to exercise the solver’s patience.
