How to Play Mahjong Solitaire

Mahjong Solitaire is a single-player tile-matching puzzle game that uses tiles from the traditional Chinese Mahjong set. Despite sharing the same tiles, Mahjong Solitaire is completely different from the four-player Chinese game of Mahjong. In Mahjong Solitaire, there are no turns, no opponents, and no drawing from a wall. Instead, all 144 tiles are arranged face-up in a layered formation, and your goal is to clear the entire layout by removing matching pairs of free tiles.

The Tile Layout

A standard Mahjong Solitaire game starts with 144 tiles arranged in a multi-layered formation. The most classic layout is the Turtle (also called the Pyramid), which stacks tiles in five overlapping layers that taper toward a peak. However, hundreds of alternative layouts exist, from simple flat grids to elaborate shapes like dragons, castles, and bridges.

• Tiles in the bottom layers are partially or fully covered by tiles in the layers above.
• Many tiles are also wedged between neighbors on the left and right, blocking their sides.
• As you remove tiles from the top and edges, previously blocked tiles become free and available for matching.

Free Tiles

Understanding which tiles are “free” is the most important concept in Mahjong Solitaire. A tile is free when it meets both of these conditions:

1. No tile is on top of it — even a tile that only partially overlaps counts as blocking.
2. At least one side (left or right) is open — if both the left and right edges are pressed against adjacent tiles on the same layer, the tile is locked.

Only free tiles can be selected. If a tile you want to match is covered or squeezed in on both sides, you must first remove the tiles blocking it.

Matching Rules

The core gameplay is simple: select two free tiles that match and they are removed from the layout. Matching rules are straightforward for most tiles, with two special exceptions:

• Standard tiles: Two tiles match if they are identical — same suit and same rank, or same wind, or same dragon. Since there are four copies of each standard tile, you can form two pairs from each type.
• Flower tiles: The four flower tiles (Plum, Orchid, Chrysanthemum, Bamboo) are each unique, but any two flower tiles match each other, regardless of which specific flowers they are.
• Season tiles: The four season tiles (Spring, Summer, Autumn, Winter) work the same way — any two season tiles match each other.

Tile Types and Counts

A Mahjong Solitaire set contains 144 tiles in total, divided into the following categories:

Winning and Losing

A game of Mahjong Solitaire ends in one of two ways:

• Win: You successfully remove every tile from the layout. All 72 matching pairs have been cleared and the board is empty.
• Loss: Tiles remain on the board, but no more matching pairs of free tiles are available. The game is stuck and cannot be completed.

Not every game is winnable. The initial tile arrangement is randomized, and some deals create layouts that cannot be fully cleared regardless of the order in which matches are made. Skilled play involves looking ahead and making matches that open up the most useful tiles below.

Strategy Tips

While Mahjong Solitaire involves luck in the initial deal, good strategy dramatically improves your win rate:

• Prioritize upper layers: Remove tiles from the highest layers first. This exposes the greatest number of hidden tiles and creates new matching opportunities.
• Match tiles that free the most: When you have a choice between two valid matches, pick the one that unblocks the most tiles underneath or beside it.
• Keep options open: Avoid immediately matching all four copies of a tile type. If three copies are free, match only two and leave the third — matching all available copies too early can leave the fourth copy stranded with no partner.
• Scan the whole board: Before making a move, look across the entire layout for all available matches. Rushing leads to missed opportunities and dead ends.
• Balance left and right: Try to clear tiles evenly from both sides of the layout. Digging too deep into one side leaves the other side locked and can result in an unsolvable position.
