Each domino (Dominoes) is composed of two squares. Each box, like a dice, has zero to six points, but there are also dominoes with a maximum of nine or twelve. Blanks are zeroes, so each square has seven points.
Cards with a maximum of six points are called Double-Six and have 28 cards.
There are seven cards with the same number of points. There are (7 * 6) / 2 = 21 pieces with different points.
Cards with a maximum of nine points are called Double-Nine, with a total of 40 cards.
There are ten cards with the same number of points. There are (10 * 6) / 2 = 30 different points.
