The short answer: Mahjong Titans is Microsoft’s Mahjong Solitaire, bundled with Windows since 2007. You get 144 tiles in one of four layouts — Turtle, Dragon, Cat, or Fortress — and you clear the board by removing tiles in matching pairs. A tile is playable only when it’s free: nothing stacked on top and at least one side open. Clear the board to win.

Mahjong Titans looks intimidating, but it isn’t hard. It’s the solitaire game that came with Windows, and once you know the two rules below, you’re playing. Here’s how to play Mahjong Titans without a manual.

What are the four layouts in Mahjong Titans?

  • Turtle — the classic stack in the shape of a turtle, and the one most people learn on.
  • Dragon — a long, winding shape that’s harder to read at a glance.
  • Cat — a compact layout with tiles packed close together.
  • Fortress — a dense, walled layout that takes longer to open up.
  • All four use the same 144 tiles — only the shape changes.

Which tiles can you actually pick?

  • A tile is free when no tile is stacked on top of it and at least one side — left or right — is open.
  • Click a free tile to select it, then click its match: same suit, same number.
  • Two matching free tiles disappear from the board.
  • Stuck? Use the Hint and Shuffle buttons — both are built into the game.

That’s the whole game. Match free pairs, keep the board open, and finish the layout. Flowers and seasons are the one exception: in Mahjong Titans any flower pairs with any flower, and any season with any season.

Is Mahjong Titans still in Windows?

Not anymore. Mahjong Titans shipped with Windows Vista and Windows 7, and newer Windows versions replaced it with Microsoft Mahjong. Browser versions of the same layouts still exist — that’s how you can play it today.

How many tiles does Mahjong Titans use?

Every layout uses the standard 144-tile Mahjong Solitaire set. The tile set never changes between layouts — only the arrangement does. Learn one layout and you already know the tiles for all four.

Is Mahjong Titans the same as Mahjong?

No. Mahjong Titans is Mahjong Solitaire, a one-player matching game. Mahjong proper — Riichi Mahjong, American Mahjong with the NMJL card — is a four-player game of hands, melds, and scoring. Same tiles, very different games.
