In Mahjong Island, a Set is three identical tiles, like three 7 Dot tiles.

Tiles: 7 Dot, 7 Dot, 7 Dot. A Set: three 7 Dot tiles.

## Where do Sets show up in a hand?

Every hand on the Island Card is written as groups of identical tiles. A group can be a Single (1), a Pair (2), a Set (3), a Quad (4), a Quint (5), or a Sextet (6). You win by completing one hand: 14 tiles that match one line on the card.

Winds can make a Set too. Three East tiles are a Set, just like three 7 Dot tiles. You can meet every tile in the guide to [Mahjong Island tiles, suits, Winds, and Dragons](/guides/mahjong-tiles).

Tiles: East, East, East. A Set of Winds: three East tiles.

## Can a Joker be part of a Set?

Yes. A Joker can fill a Set, so two 5 Crak tiles and a Joker still make a Set. A Joker can never fill a Single or a Pair. Read more in the guide to [Mahjong Island Jokers](/guides/mahjong-jokers-and-card-drops).

Tiles: 5 Crak, 5 Crak, Palm Joker. A Set with a Joker: two 5 Crak tiles and a Joker standing in for the third.

## A simple tip for beginners

Use your Jokers on Sets, not Pairs. A Joker can fill a Set, but never a Pair. For the full rules, read [how to play Mahjong Island, a simple guide for beginners](/guides/how-to-play-mahjong).
