Mahjong solitaire is forgiving early and merciless late, which means bad habits go unpunished long enough to become habits. These five are the usual suspects.
1. Taking the first pair you see
The board usually offers eight or ten legal moves. Taking whichever your eye lands on first means you are effectively playing at random, and random play kills a substantial fraction of boards.
The fix costs two seconds: before removing a pair, glance at what sits underneath and beside both tiles. Prefer the pair that frees something.
2. Clearing the easy edges first
The outer rim of the bottom layer is always accessible and always tempting. Those tiles are not going anywhere and they block almost nothing. Every move spent there is a move not spent on the central tower, which is the actual problem.
3. Splitting quartets
Two of a face free, two buried in different stacks. Taking the free pair leaves two tiles that must both surface independently. It is the single most common cause of dead boards.
Before matching any pair, ask where the other two copies are. If both are deep and separate, the free pair is probably fine. If one is about to be uncovered, wait.
The quartet check
Whenever you select a tile, look for its other three copies before confirming the match. Three seconds of checking prevents most dead ends.
4. Hoarding flowers
The eight bonus tiles match each other, which makes them the most flexible on the board. Some players save them as insurance. That is backwards — flexible tiles are useful precisely because they can be matched with whatever surfaces, so taking them early costs you nothing and clears positions.
The exception is when both visible flowers are in positions that block nothing. Then they genuinely are spare moves and can wait.
5. Ignoring the pairs counter
The readout above the board tells you exactly how tight the position is, and most players never look at it. A count that drops from twelve to four over six moves is a warning that your route is narrowing, and it arrives well before you actually run out.
A better default sequence
- Clear the peak and the 2×2 immediately.
- Work down through the 4×4 and the 6×6, spreading removals across it.
- Take quartets whenever all four are free.
- Leave the outer rim and the protruding tiles until you need them.
- From forty tiles remaining, check every option before each removal.
This is not optimal play, but it clears a large majority of boards without any deep analysis, which is a reasonable definition of a good default.
