When several identical Mahjong solitaire tiles are free, the pairs are not strategically equivalent. Compare what removing each pair exposes before clicking.
Look below and beside the candidate pair
Under standard solitaire rules, a free tile is uncovered and has at least one open left or right side. Removing two matching free tiles may uncover lower tiles or free a neighbor's side. If more than two copies are playable, prefer a pair that opens useful access over one that changes little. Check the remaining matching copies too: a move that opens one area can leave another copy difficult to reach. This is about solitaire layouts, not four-player Mahjong hands.
Try the steps
- Confirm that both candidates are actually free before comparing their value.
- For each legal pair, identify the covered tile or side access its removal would reveal.
- After removal, rescan the newly accessible area instead of continuing a memorized sequence.
Does the pair that uncovers the most tiles always win?
No. Access is a useful guide, not a proof that the layout is solvable afterward. Hidden information and the remaining matching tiles also matter. If hints or undo exist, use them to compare decisions rather than assuming they guarantee a complete solution.
