How do you play Mahjong Solitaire?

1
Locate free tiles: A tile is free if it has no tile directly on top of it and at least one left or right side completely open.
2
Match identical standard tiles: Pair exact matching tiles from Suits (Characters, Circles, Bamboos), Dragons, and Winds.
3
Match special category tiles: Any Season tile matches any other Season; any Flower tile matches any Flower.
4
Uncover trapped lower layers: Prioritize pairs that expose tall stacks or release long horizontal rows.
5
Clear the entire 144-tile formation: You win when all 72 pairs are matched and removed from the board.

Beginner Tips for Success

  • •Focus on matching top-layer tiles early to expose lower tiers.
  • •Clear the 4 long horizontal rows on the wings before internal tiles.
  • •Never match the first pair you see if another copy of that tile exists.
  • •Count remaining copies of a tile (there are 4 of each standard tile).
  • •Pairs of Seasons and Flowers match with any tile in their respective group.
  • •Use the hint and reshuffle features when logical routes stall.

Key Strategies & Advanced Techniques

1. Stack Height Prioritization

Definition: Prioritizing the removal of tiles from the tallest central stacks over flat perimeter tiles.

Example: In the classic Turtle layout, the central peak has 5 stacked tiles. Clearing the top tile reveals tiles that unlock multiple branches.

When to use: In the early game to open up internal movement.
2. Triplet Awareness Deduction

Definition: When three matching tiles are free simultaneously, carefully analyze which pair exposes more hidden tiles before removing.

Example: If three 5-Bamboo tiles are free, check which two are blocking crucial cards before making the match.

When to use: Whenever 3 identical tiles are exposed at the same time.
3. Horizontal Wing Clearance

Definition: Eliminating tiles from the far left and right extremities that block large linear chains.

Example: The outermost wing tiles on layers 1 and 2 pin entire rows. Removing them unlocks 6+ subsequent moves.

When to use: Mid-game when central stack progress slows.

A Short History of the Game

Brodie Lockard created the digital Mahjong Solitaire game in [VERIFY: 1981] on the PLATO system at the University of Illinois under the name PLATO Mah-Jongg. Activision later released it commercially in [VERIFY: 1986] as Shanghai. While utilizing traditional Chinese Mahjong tiles, the single-player matching mechanics are a modern digital creation.

Frequently Asked Questions

What makes a Mahjong tile "free" to be matched?
A tile is free if no tile rests even partially on top of it, and either its left or right side is completely clear of adjacent tiles.
Do Flower and Season tiles need to match exact symbols?
No. Any Flower tile (Plum, Orchid, Chrysanthemum, Bamboo) matches any other Flower. Any Season tile (Spring, Summer, Autumn, Winter) matches any other Season.
Are all Mahjong Solitaire deals winnable?
Random tile distributions can result in dead ends. Atelier Mahjong structures layouts using deterministic coordinate matching implemented in lib/games/mahjong.ts.
