Mahjong Solitaire is a browser tile-matching puzzle where the best move is not always the first matching pair you see. A tile has to be free before it can be removed: nothing can sit on top of it, and either its left or right side needs to be open. Once that rule is clear, the board becomes a planning problem instead of a search for identical art.
Start with pairs that open something. If two matching tiles are both on the top layer but neither one exposes a new tile or frees a blocked side, the match may be safe, but it is not urgent. A stronger early match removes tiles that are covering lower rows or locking a side of the stack. That kind of match gives the next turn more options.
Look at height before decoration. The tallest area of the board controls many future pairs because those tiles are covering other tiles. Clearing the top of a stack usually matters more than removing a flat pair from the edge. If two legal pairs are available, choose the one that reduces height or opens a crowded section.
Open sides are your second priority. A tile blocked on both left and right sides cannot move even if its matching tile is visible. When you remove a pair from the edge of a row, you may free several tiles around it. This is why matching from the outside inward often feels cleaner than pulling random exposed tiles from the middle.
Do not treat the hint button as a defeat. Hint is useful when the board feels stalled and you want to confirm whether a legal pair is visible. The better habit is to ask why the hint pair matters. If it opens a layer or side, take it. If it is only a low-value pair, check whether another legal pair opens more of the board before you commit.
Undo helps when a match closes a better route. If the remaining board suddenly has fewer useful pairs, undo the last move and compare the alternate match. The point is not to undo every mistake until the board is perfect. It is to learn which pair changed the board structure and whether a different pair would leave more paths open.
Shuffle and restart are cleanup tools, not strategy shortcuts. If the remaining board has no legal free pairs, shuffle can bring the table back into play. If the board is too tangled, restart can be faster than forcing a poor route. Before using either, check whether a hidden legal pair exists on an exposed side. Sometimes the board is not dead; it is just asking you to scan the free tiles again.
Watch for duplicate matches. If three or four of the same tile are visible, decide which two should leave first. Removing the wrong pair can strand a tile under a stack or keep a side blocked. A useful question is: which pair opens more tiles after it disappears? The answer often matters more than the fact that all four tiles match.
Your best move count and time save on this device, so a better run comes from cleaner decisions, not only faster clicks. Speed helps after you understand the table. Early in a board, move deliberately and preserve options. Later, when the remaining layout is flatter, faster matching becomes safer.
Try one board with this rule: every first-ten move should either lower the tallest stack or open a side. If a match does neither, leave it for later unless it is the only legal pair. That keeps the board flexible long enough for the harder pairs to become visible.
