3. If they don't match, both cards flip back over. Try to remember where each symbol was hiding.
4. Keep flipping until all pairs are matched. Fewer moves = a better score.

The six chess pieces:

Mahjong Solitaire is a solo tile-matching puzzle with ancient Chinese origins. The goal is simple: remove all 72 tiles from the board by matching them in pairs.

Step 1 — Understand the board. Tiles are stacked in a pyramid of layers. Tiles on higher layers sit on top of tiles below them. You must work from the top down.

Step 2 — Find a "free" tile. A tile is only available when both of the following are true:

• Nothing is resting on top of it — no tile is stacked directly above it.
• At least one side is open — there is no tile immediately to its left or to its right (or both sides are open).

Blocked tiles appear slightly dimmed and cannot be clicked. As you remove tiles, more tiles underneath become free.

Step 3 — Match and remove pairs. Click one free tile to select it (it glows green). Then click a second free tile with the same symbol — both tiles disappear from the board.

Tile types and matching rules:

Winning and losing: Clear all 72 tiles to win. If no free pairs remain on the board, the game is stuck — use the Shuffle button (available once) to rearrange the remaining tiles into new positions, or start a fresh New Game.
