What makes solitaire different
A standard board may use 144 tiles arranged in overlapping levels. You remove two matching free tiles at a time. A piece is free when nothing overlaps its top and either its left or right long edge is unobstructed. This two-part test matters: a visible tile can still be locked between neighbours, while an outside tile can still be covered from above.
The puzzle borrows tile faces from mahjong but not its hand-building rules. There are no opponents, discards, chows, pungs, or scoring calls. The challenge comes from spatial access and sequencing. Each pair alters the geometry, so a good move is one that improves access to the remaining pieces.
How to choose between equal pairs
Suppose four matching Circles are visible. One pair lies on open corners; the other includes a tile on top of a central tower. Clearing the tower piece is usually more valuable because it uncovers another layer. Before committing, check whether the remaining two copies will still be able to meet. The correct choice balances immediate access with future pairing.
Long horizontal rows deserve similar attention. Their end tiles may be the only route toward a sequence trapped in the middle. Work both ends when possible instead of stripping one side exclusively. On stacked layouts, reduce height and width together so the board does not become open in one direction but sealed in another.
Use assistance without losing the puzzle
Hints are most useful as a diagnostic tool. Scan first, choose the pair you expect the hint to reveal, and then compare. Undo is better used to test a strategic fork than to erase every imperfect move. A shuffle changes the problem more substantially and may not exist in stricter versions.
A calm session has no need for rapid clicking. Accurate symbol recognition, deliberate pair selection, and a quick rescan after each move produce more consistent results. Browser controls should support touch, keyboard focus, and readable tiles; the underlying rules should remain the same across devices.
Applied analysis
Worked example: four identical tiles
Imagine that four East Winds are still on the board. Two are free on harmless outside corners, one caps the central stack, and the fourth is buried directly below it. Pairing the two corners feels safe, but it removes the only partners that can release the stacked Winds in sequence. The stronger line pairs one corner with the upper central tile. That move exposes the fourth Wind and leaves a legal partner available. This small example shows why duplicate location matters more than the first matching pictures you notice.
Quick answers
Questions players ask
Can a visible tile still be blocked?
Yes. Visibility is not enough: a tile must also have no overlapping tile above it and at least one accessible long side.
Are Flower tiles identical matches?
Flowers usually match as a group, so two different Flower faces can form a legal pair. Seasons follow the same group rule separately.
