"This puzzle is traditionally posed as a challenge to create seven square frames with all 28 dominoes so that the sums of the numbers of dots are the same at all four sides. Transum has simplified the problem slightly by showing what the totals are for the seven square frames. Are there any other solutions to the traditional problem which produce different side totals? Please let us know!
[Tip: If the puzzle area is too large for your screen change the view zoom factor until you can see the whole area.]."
