Mahjong Solitaire Rules

Mahjong Solitaire is the tile-matching puzzle most people picture when they hear "mahjong game" on a computer or phone. A pyramid of 144 tiles sits in front of you, and you clear it two tiles at a time. The rules take a minute to learn, yet the best players still think carefully about every move. This guide covers the official rules, the classic turtle layout, the special flower and season tiles, and the strategies that separate a lucky win from a reliable one.

Where Mahjong Solitaire comes from

Despite the name, Mahjong Solitaire is not an old Chinese game. The traditional game of mahjong is played by four people and is closer to rummy than to a puzzle. The single-player version was popularized in the early 1980s by a computer game called Mah-Jongg, and later by titles such as Shanghai. Those games borrowed the tiles and invented a new challenge: remove every tile from a stacked layout by matching free pairs.

Because the puzzle only uses the tiles, you do not need to know anything about four-player rules. Recognizing matching pictures is enough.

The tiles

A full Mahjong Solitaire set has 144 tiles:

• Suits: characters, circles (dots) and bamboo, numbered one to nine, four copies of each. That is 108 tiles.
• Honors: four winds (East, South, West, North) and three dragons (red, green, white), four copies of each. That is 28 tiles.
• Flowers: four different flower tiles, one copy each.
• Seasons: four different season tiles, one copy each.

Suit and honor tiles must match exactly: a five of bamboo only pairs with another five of bamboo. Flowers and seasons are the exception. Any flower matches any other flower, and any season matches any other season, even though each picture is different.

The layout

Tiles are stacked in layers to form a shape. The most famous shape is the turtle: a wide rectangular base with shorter rows at the ends, several smaller layers stacked in the middle, and a single tile on top. Other layouts include the fortress, the dragon, the cat and dozens of custom shapes. Every layout follows the same rules, but taller layouts hide more tiles and demand more planning.

The one rule that matters: free tiles

You may only select a tile that is free. A tile is free when both of these are true:

1. Nothing is on top of it. No tile in a higher layer covers any part of it.
2. One long side is open. There is no tile directly touching it on the left, or no tile directly touching it on the right.

Tiles touching above or below on the same layer do not matter; only left and right do. So a tile in the middle of a long row is blocked until one of its horizontal neighbors has been removed.

Select two free tiles with matching faces and both are removed. Repeat until the board is empty. If no two free tiles match, you are stuck. Some games then offer a shuffle, a hint or an undo; others count the round as lost.

A step-by-step first game

1. Find all free tiles. Start with the top tile and the tiles at the far left and right of each row.
2. Look for matches among free tiles only. Ignore anything that is covered or blocked for now.
3. Prefer matches that free new tiles. Removing a tile that sits on top of others, or at the end of a long row, opens more choices.
4. Keep track of the four copies. Before matching, check where the other two copies of that tile are.
5. Repeat until the board is clear or until no free pair remains.

Strategies for winning more often

Mahjong Solitaire looks like luck, but good habits dramatically improve your win rate.

Unblock long rows first

The longest horizontal rows lock up the most tiles, because every tile in the row waits for its neighbor. Working inward from the ends of long rows frees tiles quickly and keeps your options open.

Uncover stacks early

Tiles buried under several layers are the ones you cannot see. The sooner you remove the tiles above them, the sooner you learn what is underneath and the fewer surprises you face late in the game.

Think about all four copies

Each tile face appears four times. If all four are free, remove them as two pairs and move on. If only three are free, be careful: pick the two whose removal helps the most, and remember that the fourth copy must still be reachable by the third.

Avoid burying a pair

The classic trap is removing two copies of a tile while the last two copies sit one on top of the other. The lower tile can never become free, because its only partner covers it. Before matching, check that the remaining copies are not stacked on each other.

Use flowers and seasons wisely

Because any flower matches any flower, these tiles are flexible. Save them for when they unlock something important rather than removing them the moment you see them.

Take your time

Most versions have no timer, and the board never changes by itself. A few seconds of thought before each match saves many restarts.

Mahjong Solitaire vs. Mahjong Connect

Both games use mahjong tiles and remove matching pairs, but they feel quite different.

If you enjoy calm puzzles with everything visible, try Mahjong Connect. Our Pet Mahjong boards are animal-shaped Connect puzzles with no timer and no sign-up.

Common questions about scoring

Classic Mahjong Solitaire has no official scoring. Many apps add points for speed or combos, but those are extras. The traditional goal is simply to clear the whole layout. When comparing yourself with friends, the most meaningful measure is how often you clear the board, not how fast.

Etiquette and variants

Because it is a single-player game, there is no etiquette to worry about, but there are variants worth knowing:

• Open tiles: all layers are shown slightly offset so you can see every tile. This makes the game much easier.
• Solvable deals: the game builds the layout backwards from a winning sequence so at least one solution exists.
• Timed modes: some apps add a clock. If you find timers stressful, choose an untimed mode.
• Themed tiles: some games replace the traditional faces with animals, fruit or large-print symbols for easier reading.
