Domino — 2/2 — free printable diagram

How many spots are on the 2–2 domino?

This domino has 2 spots on one half and 2 spots on the other, so it is worth 4 in total.

One half

2

Other half

2

Total spots

4

Addition

2 + 2 = 4

Double?

Yes

• Each half of a domino carries its own number of spots, and the tile's value is the two halves added together: 2 + 2 = 4.
• Both halves match, so this tile is a double — the double 2. A double-six set has seven doubles, one for each number from blank to six.
• As a doubling fact it reads double 2 is 4, and backwards as half of 4 is 2.
• 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.
