The domino points

Surely you have played many domino games, so the following question should be easy to answer:

How many points does a complete domino game have?

Solution

The sum of all points equals 168. We have 7 chips of each type (white, 1, 2, 3, 4, 5 and 6) and we know that one of the chips is double so we have 8 repetitions of each number of points, that is: 8 * 6 + 8 * 5 + 8 * 4 + 8 * 3 + 8 * 2 + 8 * 1 + 8 * 0 = 168
