THE DOMINO FRAME PUZZLE

It will be seen in the illustration that the full set of twenty-eight dominoes is arranged in the form of a square frame, with `6` against `6, 2` against `2`, blank against blank, and so on, as in the game. It will be found that the pips in the top row and left-hand column both add up `44`. The pips in the other two sides sum to `59` and `32` respectively. The puzzle is to rearrange the dominoes in the same form so that all of the four sides shall sum to `44`. Remember that the dominoes must be correctly placed one against another as in the game.
