Mahjong Solitaire

Mahjong Solitaire, also called Mahjongg or Shanghai, is the tile-matching puzzle built into Windows for decades. Match pairs of free tiles to clear the stack.

How to play Mahjong Solitaire

  • A tile is free when nothing sits on top of it and its left or right side is open.
  • Click two identical free tiles to remove them.
  • Flowers match any flower, seasons match any season.
  • Clear the whole board to win. Use hint, shuffle or undo if you get stuck.

Tips that actually help

  • Always clear the top layers first — a buried tile is worth nothing.
  • Never take a pair just because it is visible; check what it unlocks underneath.
  • Save flowers and seasons for the end, when they act as a wildcard.

What is Mahjong Solitaire?

Mahjong Solitaire is a single-player matching puzzle that uses a full set of 144 mahjong tiles stacked in a layered shape. The best known layout is the turtle, the one Microsoft shipped with Windows as Mahjong Titans and later Microsoft Mahjong.

Is this the same as playing mahjong?

No. The four-player game is a competitive tile game with scoring rules and drawing from a wall. Mahjong Solitaire only borrows the tiles. It is a pure puzzle: no opponents, no scoring hands, no luck of the draw.

Why it stays popular

The rules take ten seconds to learn, but a hard layout takes real planning. That combination — easy to start, hard to master — is why it has survived in browsers for more than twenty years.

Frequently asked questions

How many tiles are on the board?

The classic turtle layout uses all 144 tiles from a standard mahjong set.

Can every layout be solved?

Not always — some shuffles are unwinnable. That is why the game offers shuffle and undo.
