how many dominoes in a set
A standard, traditional domino set has 28 tiles , often called a double- six set.
Quick answer
- Most commonly, when people say a “full domino set,” they mean a double-six set with 28 dominoes.
- Other common sets have more tiles:
- Double‑9: 55 tiles
* Double‑12: **91 tiles**
* Double‑15: **136 tiles**
* Double‑18: **190 tiles**
Why 28 in a standard set?
A double‑six set includes every possible pair of numbers from 0 to 6 (including doubles like 0‑0, 1‑1, …, 6‑6).
Mathematically, a double‑nnn set has (n+1)(n+2)2\frac{(n+1)(n+2)}{2}2(n+1)(n+2) tiles, which gives 28 when n=6n=6n=6.
