How many spots are on the 6–6 domino?

6

Other half

6

Total spots

12

Addition

6 + 6 = 12

Double?

Yes

• Each half of a domino carries its own number of spots, and the tile's value is the two halves added together: 6 + 6 = 12.
• Both halves match, so this tile is a double — the double 6. A double-six set has seven doubles, one for each number from blank to six.
• As a doubling fact it reads double 6 is 12, and backwards as half of 12 is 6.
• A full double-six set has 28 tiles: every pair of numbers from blank to six once each, counting a tile and its turned-round twin as the same tile.
